Clwb Ifor Bach (English: Little Ivor's Club, Welsh pronunciation: [ˈklʊb ˈivɔr ˈbaːχ]) is a Cardiff nightclub, music venue, Welsh-language club and community centre. It is known to the Cardiff Welsh-speaking community as Clwb (English: Club) and is often known by others on the Cardiff music scene as The Welsh Club.
Clwb Ifor Bach is used as a social centre by Welsh speaking people in Cardiff, as well as by many non-Welsh speakers. Until recent years, the club had a number of regular members only nights. This policy has been discontinued. Clwb Ifor Bach is the focal point for many Welsh-medium organisations and events in the area: social, educational, sporting and otherwise. English and Welsh are spoken equally throughout the club, and most staff are required to be bilingual. No anti-Welsh sentiment is tolerated in the club.
Clwb Ifor Bach is located in central Cardiff, halfway down Womanby Street, a lane running from the front of Cardiff Castle, parallel to High Street/St Mary Street). At either end of Womanby Street are The City Arms, opposite the Millennium Stadium, and Dempsey's Irish Bar, opposite the castle. The club faces the rear of the Wetherspoons pub 'The Gatekeeper'.
Clwb Ifor Bach has existed since 1983 and was founded by Cymdeithas Clwb Cymraeg Caerdydd, a society formed with the purpose of establishing a Welsh language social club. The Chair was Welsh politician Owen John Thomas. The club is named for Ifor Bach, a famous rebel leader against English rule in the 12th century.
