Every NBA Team's Best Undefeated Start to a Season

The longest season-opening winning streak for every current NBA franchise, plus the historic Washington Capitols.

NBA Record: Golden State Warriors - 24-0 (2015-16)

Golden State owns the longest undefeated start to an NBA season. The Warriors won their first 24 games in 2015-16 before suffering their first loss.

This page lists the best undefeated start in the history of every current NBA franchise. The streak begins with a team's first regular-season game and ends with its first loss.

Franchise history follows continuous franchise lineage through relocations and name changes. Oklahoma City's record therefore includes the Seattle SuperSonics era, while other relocated franchises retain records established under their previous names.

The Washington Capitols are retained as a separate historical entry because the original NBAHoopsOnline record included the defunct BAA franchise and its remarkable 15-0 start in 1948-49.

Franchises That Have Never Started 5-0

Three current NBA franchises have never opened a season with five consecutive victories.

Brooklyn Nets: The franchise record is 4-0, set by the 2002-03 New Jersey Nets.

Orlando Magic: Orlando's best start is 4-0, set during the 2020-21 season.

Charlotte Hornets: Charlotte has the shortest franchise-best undefeated start among current NBA teams at 3-0, set in 2021-22.

Historical Notes and Records

Golden State Warriors: Golden State's 24-0 opening in 2015-16 is not merely the Warriors' franchise record; it is the longest undefeated start in NBA history. The Warriors eventually finished 73-9 but lost to Cleveland in the NBA Finals.

Cleveland Cavaliers: Cleveland established a new franchise record in 2024-25 by winning its first 15 games. The previous Cavaliers record had been an 8-0 start in 1976-77.

Houston Rockets: Houston began the 1993-94 season 15-0 and went on to win the first NBA championship in franchise history. The Rockets are one of the few teams whose franchise-record undefeated opening ended with a championship.

Washington Capitols: The Capitols opened the 1948-49 BAA season 15-0. The defunct franchise is retained separately on this page because its start remains one of the greatest in professional basketball history.

Oklahoma City Thunder / Seattle SuperSonics: The franchise record remains the 12-0 start established by the 1982-83 Seattle SuperSonics. Oklahoma City began both the 2024-25 and 2025-26 seasons 7-0, and reached 8-0 in 2025-26, but that did not surpass Seattle's franchise record.

San Antonio Spurs: San Antonio established a new franchise record in 2025-26 by starting 5-0. Before that season, the Spurs had never opened an NBA season with five consecutive victories.

Detroit Pistons: Detroit owns one of the strangest records on the page. The 1970-71 Pistons started 9-0 but finished only 45-37 and missed the playoffs. It remains the best undefeated start by an NBA team that ultimately failed to reach the postseason.

Orlando Magic: The 2020-21 Magic started 4-0 before finishing only 21-51. That is the fewest final-season victories by any team represented on this list.

Toronto Raptors: Toronto's 6-0 start in 2018-19 remains the best in franchise history. The Raptors eventually defeated Golden State in the NBA Finals to win their first championship.

Miami Heat: Miami's 5-0 start in 2011-12 is relatively modest compared with many teams on this page, but the Heat ultimately won the NBA championship that season.

About the Records

A team's best start is its longest winning streak beginning with the first game of the regular season. The streak ends immediately when the team suffers its first loss.

Franchise records include continuous franchise history through relocations and name changes. For example, the Oklahoma City Thunder record includes the Seattle SuperSonics era.

Historical team names are used in the notes when appropriate so that the record is presented in the context in which it occurred.

The Washington Capitols are included as an additional historical BAA franchise because their 15-0 start remains tied for the second-longest undefeated opening in NBA/BAA history.

Updated through the 2025-26 NBA season. Franchise records include historical names and relocations where applicable.
