Long Beach State Beach men's basketball

The Long Beach State Beach men's basketball team represents California State University, Long Beach in Long Beach, California. The school's team competes in the Big West Conference. Because they won the 2024 Big West Conference men's basketball tournament, the team received an automatic bid to the 2024 NCAA Division I men's basketball tournament; the last time Long Beach State competed in this tournament was 2012. The Beach is currently coached by Chris Acker. Long Beach State officially changed their nickname with the NCAA to "Beach" from "49ers" prior to the 2019–20 season.

In the 2006–07 season, the 49ers finished with a 24–8 (12–2) record, the Big West conference championship, and the school's first trip to the NCAA tournament in 12 years. Star guard Aaron Nixon was named Big West player of the year, as well as being selected as an AP Honorable Mention All-American.

In 2008, the team began a three-year probation term, vacated 18 victories from their 2005–2006 season, and reduced scholarships and recruiting in order to keep eligibility for postseason play.
