On 13 March 2012, Bogut and Stephen Jackson were traded to the Golden State Warriors in exchange for Monta Ellis, Ekpe Udoh and Kwame Brown.
According to the Warriors, he underwent surgery in April to "clean out loose particles and bone spurs in the ankle".
He sat out the 2012–13 preseason, but played in four of the first five regular season games, averaging just 6.0 points and 3.8 rebounds.
He was then declared out indefinitely.
He received Regenokine treatment to aid his recovery in late November, and it was also revealed that his procedure in April was more serious microfracture surgery than previously thought.
Bogut returned on 28 January 2013, recording 12 points, 8 rebounds, 2 assists and 4 blocks in a road win over the Toronto Raptors.
On 2 May 2013, in Game 6 of the first round of the playoffs, Bogut recorded playoff career-highs of 14 points and 21 rebounds.
He also became the first Warriors player with 20 playoff rebounds since Larry Smith had 23 on 12 May 1987 against the Los Angeles Lakers.

On 25 October 2013, Bogut signed a three-year contract extension with the Warriors.
Despite another injury-riddled season in 2013–14, Bogut still finished 10th in NBA Defensive Player of the Year voting and became the first player in franchise history to average at least 10 rebounds per game while shooting 60 percent from the field.

After playing well through the first 19 games of the 2014–15 season, Bogut injured his right knee on 8 December 2014 against the Minnesota Timberwolves and subsequently missed 12 games.
He returned to action off the bench against Indiana on 7 January 2015, recording 4 points and 8 rebounds in a 117–102 win.
On 2 March 2015, he scored a season-high 16 points in a loss to the Brooklyn Nets.
On 7 April 2015, he recorded 8 points and a career-high 9 blocks in a loss to the New Orleans Pelicans.
Bogut and the Warriors won the 2015 NBA Finals after defeating the Cleveland Cavaliers in six games.

Disappointed in the way he ended the 2014–15 season, Bogut removed all processed sugars from his diet during the 2015 off-season and subsequently came into training camp in October 2015 with improved athleticism, having dropped 10 kilograms.
On 9 February 2016, Bogut had a season-best game with 13 points, 11 rebounds, three steals and a season-high six blocked shots in a 123–110 win over the Houston Rockets.
The Warriors broke the NBA record for most wins in a season with 73, eclipsing the 72 wins set by the 1995–96 Chicago Bulls.
In Game 5 of the Warriors' Conference Finals match-up with the Oklahoma City Thunder, Bogut recorded a playoff career-high 15 points and 14 rebounds to help the Warriors send the series to a Game 6 with a 120–111 win at home, cutting the Thunder's advantage in the series to 3–2.
The Warriors went on to win the series in seven games and advanced to the NBA Finals for the second straight year.
The Warriors would again face the Cleveland Cavaliers.
On 15 June 2016, he was ruled out for six to eight weeks with a left knee injury.
