Paul Noonan is an Irish singer from Lucan, County Dublin, and lead vocalist of the band Bell X1.

During the early 90s, while attending Salesian College secondary school in Celbridge, Noonan joined the band Juniper as drummer. He later attended university at Trinity College, Dublin and completed a degree in computer engineering. Juniper had by this time gained a significant following and signed a multi-album deal with Polygram in 1997. Two singles were recorded before frontman Damien Rice left the band and moved to Tuscany, Italy to work on solo material. The remaining band members continued to play together and eventually formed Bell X1 with Noonan as their vocalist. Rice, meanwhile, has released solo albums including O and 9.

Noonan plays drums on all of Bell X1's studio recordings and has been known to occasionally play drums at live performances if a session drummer is not available.[citation needed] Currently, Tim O'Donovan (who also fronts electro-pop act NeoSuperVital) is the band's live drummer. Noonan most commonly plays guitar, percussion and kazoo. Noonan has also appeared, and was among the producers on the 2006 charity album, The Cake Sale. In October 2007, he played drums as part of Irish singer Cathy Davey's touring band and regularly works with Gemma Hayes where he has featured on her EPs, her debut album Night On My Side providing backing vocals and drums and her 2008 album The Hollow of Morning, he will also appear on her fourth album in May 2011.
