2019–20 Golden State Warriors season

The 2019–20 Golden State Warriors season was the 74th season of the franchise in the National Basketball Association (NBA), and its 58th in the San Francisco Bay Area. The Warriors entered the season as the five-time defending Western Conference champion and runners-up in the 2019 NBA Finals, where they lost to the Toronto Raptors in six games. The Warriors moved from the Oracle Arena (now Oakland Arena) in Oakland to the new Chase Center in San Francisco before the start of the season, the first time the team had played in the city since the 1970–71 season.

This season saw the departures of Kevin Durant and Andre Iguodala, and thus the break up of the Hamptons Five. After considering signing with teams such as the New York Knicks and Los Angeles Clippers, Durant left in a sign-and-trade with the Brooklyn Nets, with the Golden State Warriors acquiring All-Star guard D'Angelo Russell as part of the deal. Iguodala was traded to the Memphis Grizzlies after six seasons with the Warriors, in which he won three championships and a Finals MVP. Russell would then be traded to the Minnesota Timberwolves for former #1 pick Andrew Wiggins at the trade deadline in February 2020.

Despite lofty expectations, the Warriors got off to a 4–16 start, their worst since the 2000 season. Injuries were a major reason for the poor start. All-Star SG Klay Thompson missed the entire regular season with an ACL tear he suffered during Game 6 of the 2019 NBA Finals. Stephen Curry was injured on October 30, 2019, which required surgery to repair his broken second metacarpal. Curry played in just five of the Warriors' 65 games.

With their 33rd loss against the Dallas Mavericks on January 14, 2020, the Warriors failed to reach 50 wins for the first time since 2013. From the end of December to the middle of January, the team suffered a 10-game losing streak, the first time they have lost 10 games in a row since 2002. They also suffered their first losing season since 2012 following their 42nd loss to the Miami Heat. With their March 10 loss to the Clippers, the Warriors were eliminated from the playoffs for the first time since 2012 and did not make the NBA Finals for the first time since 2014, ending five consecutive Finals appearances.

In response to mounting concerns over the COVID-19 pandemic by public health officials, the season was suspended by the league officials following the games of March 11 after it was reported that then Utah Jazz center Rudy Gobert tested positive for COVID-19. This came after the Warriors announced that their game against the Brooklyn Nets the next day would be played behind closed doors. On June 4, 2020, it was announced by the NBA Board of Governors approved a plan that would restart the season with 22 teams returning to play in the NBA Bubble on July 31, 2020, which was approved by the National Basketball Players Association (NBPA) the next day. The Warriors, with the Western Conference's (and the league's overall) worst record at the time of the season's suspension, were not among them, effectively ending the team's season. This was the first time the team had the worst season record in the league in franchise history.
