List of professional sports team owners

This is a list of individuals, groups of individuals, and companies who have owned and operated a professional sports organization. The list is organized first by sport, then by franchise or team, then by Owner. If an organization has gone through a significant change (e.g. the team has moved and/or changed names), that information is noted after the years of ownership.

(Listed by Constructor)

In Japanese baseball, teams are traditionally owned by companies and bear that company's name. Only one team in recent years has not borne a corporate name—the Yokohama BayStars went without a corporate name from 1993 through 2011 because its owner chose not to attach its name to the team. The company identifier is indicated in bold type in the owner list.

Note: This list reflects the actual control of the franchise. The ownership structure is considerably more complicated. Notably, it was reported that Al Davis owned only a 47% stake in the team when he died in 2011, although he exercised near-total control as the president of the team's general partner. His widow Carol and son Mark inherited his interest in the team, with Mark exercising day-to-day control. See the relevant section of the team article for more details.
