As coach:
 Mark Ellsworth Madsen (born January 28, 1976) is an American basketball coach and former NBA player who is the head coach of the California Golden Bears of the Atlantic Coast Conference. Due to his hustle and physical style of play, he received the nickname "Mad Dog" while playing for the San Ramon Valley High School Wolves, and the moniker continued during his time with the Stanford Cardinal and beyond. He played professionally in the National Basketball Association (NBA) with the Los Angeles Lakers, winning two NBA championships. He also played for the Minnesota Timberwolves.
 Madsen played NCAA basketball at Stanford, where he finished his career ranked in the school's career top 10 in blocks and rebounds.  In addition, Madsen helped the Cardinal to four NCAA tournament appearances, including a Final Four berth in 1998. Perhaps his signature moment at Stanford was his dunk and free throw that gave Stanford a lead over Rhode Island, propelling the team into the Final Four, where it lost to eventual champion Kentucky. Madsen was a two-time All-American and a two-time All-Pac-10 selection.
 The Los Angeles Lakers selected Madsen in the first round (29th pick overall) of the 2000 NBA draft. He contributed to the Lakers' NBA championships in 2001 and 2002, and became well known for his goofy dances at the victory parades for those championships.
 Talking about his prime with the Lakers, Shaquille O'Neal said that the only player who could thwart him from his dominant play was Madsen. "He used to beat me up in practice", O'Neal said.
 Madsen signed with the Timberwolves as a free agent before the start of the 2003–04 NBA season. He played six seasons for the Wolves.
 On July 20, 2009, Madsen was traded to the Los Angeles Clippers along with Craig Smith and Sebastian Telfair in exchange for Quentin Richardson. On August 21, 2009, he was waived by the Clippers.
 Madsen's final NBA game was played on April 15, 2009 in a 90-97 loss to the Sacramento Kings. In his final game, Madsen was the team's starting power forward, but he played for only 9 and a half minutes and recorded no stats. His career averages were 2.2 points, 2.6 rebounds, and 0.4 assists in 11.8 minutes played per game.
 Following being waived, Madsen was hired as the assistant coach for the Utah Flash of the NBA Development League (D-League). In 2012, he was hired as an assistant coach at Stanford. On May 13, 2013, he was named head coach of the Los Angeles D-Fenders, a D-League team owned by the Los Angeles Lakers. 
 On July 19, 2013, Madsen was promoted to a player development coach position with the Lakers. 
On September 16, 2014 Madsen was promoted to full-fledged assistant coach by Byron Scott. After Byron Scott was dismissed as head coach of the Lakers, new head coach Luke Walton retained Madsen as assistant coach on July 1, 2016.
 Madsen was hired as the head coach at Utah Valley University on April 14, 2019.
 Madsen was hired as the head coach at the University of California, Berkeley on March 29, 2023. Madsen is the 19th men's basketball head coach in Cal history. 
 Madsen is a member of the Church of Jesus Christ of Latter-day Saints. Madsen speaks Spanish, acquiring the language from a two-year mission abroad in Málaga, Spain on behalf of his church following his graduation from high school.
 As a youth, Madsen attained the rank of Eagle Scout and credits Scouting with teaching him about leadership, character and mentoring.
 In fall 2010, Madsen enrolled in the Stanford Graduate School of Business.  In June 2012, he received an M.B.A. degree with a Certificate in Public Management.
 Madsen married Hannah Harkness on September 3, 2016.
