Bath Rugby are a professional rugby union club in Bath, Somerset, England. They play in Premiership Rugby, England's top division of rugby. Founded in 1865 as Bath Football Club, since 1894 the club has played at the Recreation Ground in the city centre.

Bath Rugby is one of the most successful clubs in England, having won 18 major trophies. It was particularly successful between 1984 and 1998, when it won 10 Domestic Cups, 6 League titles, and became the first English side to win the European Cup in 1998. In 2008, Bath also won the European Challenge Cup, the continent's second-tier competition. However, the club has yet to win a major trophy since then.

Bath is one of only three clubs never to have been relegated from the top division of English rugby. Bath finished 2nd in the 2023–24 Premiership Rugby season, losing the play off final, this entitles them to play in the 2024-25 European Rugby Champions Cup.

Bath also have a longstanding rivalry with Leicester Tigers.
