The Oakland Athletics relocation to Las Vegas is an ongoing effort by ownership of the Oakland Athletics of Major League Baseball (MLB) to relocate the franchise from Oakland, California to Las Vegas, Nevada. The team has been based in Oakland since 1968, where it has won four World Series titles. Their relocation would make them the second major sports franchise to move from Oakland to Las Vegas, following the Oakland Raiders of the National Football League (NFL) making the same move in 2020. With four locations, the A's have had the most homes of any MLB team.

The Oakland Athletics are an American professional baseball team based in Oakland, California. The Athletics compete in Major League Baseball (MLB) as a member club of the American League (AL) West Division. The team currently plays its home games at the Oakland Coliseum, with plans to temporarily move to Sutter Health Park in West Sacramento, California, for the 2025–2027 seasons, prior to their permanent move to Las Vegas. The nine World Series championships, fifteen pennants, and seventeen division titles that the A's have won throughout their history is the second-highest in the American League after the New York Yankees.
