2026 Redistricting: Which States Have New House Maps

As of October 13, 2026, nine states will hold the November 3, 2026 House elections under new congressional maps: Alabama, California, Florida, Louisiana, North Carolina, Ohio, Tennessee, Texas and Utah, according to Ballotpedia ^[1]. Those nine states elect 173 of the 435 House members; under their old maps in 2024, Republicans won 95 of those seats and Democrats 78 ^[2]. Missouri and Virginia also approved new maps, but neither is in effect for 2026: the U.S. Supreme Court held on September 25, 2026 that Missouri must use its 2022 map, and Virginia will use its 2021 map after its redraw was blocked in state court ^[3][4].

Which states have new congressional maps for 2026?

Redistricting normally happens once a decade, after the census. Mid-decade redistricting means drawing new district lines between censuses, here between the 2024 and 2026 elections. Ballotpedia notes that before 2025, only two states had conducted voluntary mid-decade redistricting since 1970 ^[1]. The table lists every state whose map changed for 2026, plus the two states whose new maps are not in effect.

Which maps did state legislatures redraw?

Texas

Governor Greg Abbott signed the new map on August 29, 2025; The Texas Tribune reported that it was designed to create five new Republican districts ^[5]. A three-judge federal panel blocked the map in November 2025, and the U.S. Supreme Court then allowed Texas to use it for the 2026 elections, the Associated Press reported on December 5, 2025 ^[6]. Under the old map, Democrats won 13 of 38 seats and Republicans 25 in 2024 ^[2].

North Carolina

The General Assembly gave final approval on October 22, 2025; the governor's signature is not required for congressional maps in North Carolina ^[10]. The Associated Press reported that the map targets the 1st District, held by Democrat Don Davis, as Republicans seek an 11th seat, and that a federal panel denied requests to block it on November 26, 2025 ^[10]. In 2024, the old map produced 4 Democratic and 10 Republican seats ^[2].

Florida

The Legislature passed a new map in April 2026 and Governor Ron DeSantis signed it on May 4, 2026 ^[1][13]. WFLX reported that the map could help Republicans gain as many as four seats, and plaintiffs sued the same day under the state's Fair Districts Amendment ^[13]. On June 10, 2026, the Florida Supreme Court ruled 6-1 that it lacked jurisdiction to review a lower court's refusal to block the map, leaving it in place for 2026 while the lawsuit continues ^[14]. Florida's 2024 result was 8 Democratic and 20 Republican seats ^[2].

Tennessee

The General Assembly approved a new map on May 7, 2026, and Governor Bill Lee signed it ^[15]. USA TODAY reported that the map divides Memphis among three districts, and quoted the Senate sponsor, Senator John Stevens, as saying it "was drawn to maximize Republicans' ability to win nine congressional seats" ^[15]. A federal court denied a request to block the map in July 2026, allowing it to govern the August primary and the November general election ^[16]. In 2024, Tennessee elected 1 Democrat and 8 Republicans ^[2].

Louisiana

The U.S. Supreme Court ruled on April 29, 2026 that Louisiana's 2024 map, which included a second majority-Black district, was an unconstitutional racial gerrymander ^[1][17]. The Legislature passed a replacement map, Senate Bill 121, and Governor Jeff Landry signed it on May 29, 2026; FOX 8 reported that it eliminates one of the state's two Black-majority districts and that the bill's author said it is designed to help Republican candidates ^[17]. Louisiana's House primary is on November 3, 2026 and its general election on December 12, 2026 ^[18]. The old map produced 2 Democratic and 4 Republican seats in 2024 ^[2].

Which maps came from voters, commissions or courts?

California

Proposition 50 allowed a legislatively drawn map to replace the one drawn by the California Citizens Redistricting Commission through 2030 ^[1]. Voters approved it on November 4, 2025 by 7,453,339 votes (64.4%) to 4,116,998 (35.6%) ^[7]. NBC Los Angeles reported that the measure aims to help Democrats gain five seats ^[9]. On February 4, 2026, the U.S. Supreme Court denied an application to block the map ^[8]. Under the old map, Democrats won 43 of 52 seats and Republicans 9 in 2024 ^[2].

Ohio

Ohio was required to redraw because its previous map passed without bipartisan support, and a state constitutional amendment gives such maps a shorter life ^[1]. The seven-member Ohio Redistricting Commission approved a new map unanimously on October 31, 2025, with both Democratic members voting yes; it applies from 2026 until 2031 ^[11]. WYSU reported that the map shifts districts in Cincinnati and Toledo toward Republicans and a district around Akron toward Democrats ^[11]. The 2024 result was 5 Democratic and 10 Republican seats ^[2].

Utah

A state judge struck down the Legislature's map in August 2025 in a case over the Legislature's changes to Proposition 4, a voter-approved redistricting initiative, then chose a plaintiffs' map in November 2025 ^[1]. KUER reported that the map creates a district centered on Salt Lake County that is favorable to Democrats, and that the Utah Supreme Court dismissed the Legislature's appeal on February 20, 2026 ^[12]. All four Utah seats were won by Republicans in 2024 ^[2].

Alabama

Alabama used a court-drawn map in 2024 after courts blocked the Legislature's 2023 map ^[1]. On June 2, 2026, the U.S. Supreme Court lifted the lower-court order and allowed the 2023 map to be used in 2026; NPR described the result as six Republican-leaning districts and one Democratic-leaning district ^[19]. In 2024, Alabama elected 2 Democrats and 5 Republicans ^[2].

Which redistricting efforts did not take effect for 2026?

Missouri

The Legislature adopted a new map in September 2025; according to Ballotpedia, the map Governor Mike Kehoe proposed for the special session would net Republicans one House seat ^[1]. Opponents filed more than 300,000 signatures for a veto referendum, and on September 3, 2026 the Missouri Supreme Court held that the map cannot take effect unless voters approve it at the November 2026 election ^[3]. The August primary was held under the 2025 map, but on September 25, 2026 the U.S. Supreme Court said that, as a matter of state law, the 2022 map and not the 2025 map must be used in the 2026 congressional election ^[3]. In 2024, the 2022 map produced 2 Democratic and 6 Republican seats ^[2].

Virginia

Virginia's Legislature approved a constitutional amendment and a map that, according to Ballotpedia, aimed to produce 10 Democratic districts and 1 Republican district, and voters approved the amendment on April 21, 2026 ^[1]. The Supreme Court of Virginia blocked it on May 8, 2026, and on May 15, 2026 the U.S. Supreme Court declined to restore it; Governor Abigail Spanberger said the 2026 elections would use the districts drawn in 2021 ^[1][4]. Those districts produced 6 Democratic and 5 Republican seats in 2024 ^[2].

Indiana and other states

The Indiana Senate voted 31-19 on December 11, 2025 to reject a map that, the Associated Press reported, was designed to give Republicans all nine of the state's seats ^[20]. Ballotpedia's list of states with new maps for 2026 does not include Maryland, New York or South Carolina, where redistricting efforts or court cases did not produce a new map for this election ^[1].

Nine states with 173 House seats will vote under new congressional maps on November 3, 2026, while new maps passed in Missouri and Virginia are not in effect.

What is California's Proposition 50?

A constitutional amendment approved on November 4, 2025 with 64.4% of the vote that lets California use a legislatively drawn congressional map through 2030 instead of the commission map ^[1][7]. Democrats won 43 of 52 California seats under the old map in 2024 ^[2].
