The al-Manar Centre (sometimes referred to as 2 Glynrhondda Street) is a mosque in the Cathays district of Cardiff, Wales. Founded in 1992, it describes itself as being "one of [the] Ahlus-Sunnah organisations". A widely circulated claim holds that a mosque was registered at this address in 1860, which would make the Al-Manar Centre the oldest mosque in the United Kingdom.
