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. Despite the injuries, the Warriors' had a bright spot in second-round draft pick Eric Paschall who was named to the NBA All-Rookie First Team in 2020.

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, 2020. On June 4, 2020, it was announced that the NBA Board of Governors had approved a plan in which 22 teams would resume the season behind closed doors; the plan was approved by the National Basketball Players Association (NBPA) the following day. The Warriors, with the league's overall worst record (15-50) at the time of the season's suspension, were not among the 22 teams selected. The 2019-20 season was the first season in franchise history in which the Warriors had the worst record in the league.
