YFriday were a British Christian rock and worship band from Newcastle upon Tyne. From their beginning in 1994 until they split in 2010, they gained popularity amongst Christian music fans around the world, particularly in the United Kingdom. In 2010, YFriday announced that they were commencing their final months before disbanding later in the same year, after releasing a number of successful albums.

The group was formed in 1994, originally as the house band for a monthly evangelistic outreach event run by Youth for Christ called WhyFriday?. The WhyFriday? outreach programme initially had a regular attendance of about 50-60 young people, but this steadily grew and the programme, now called IXth Hour, is currently held in the Newcastle City Hall, and has around 800 attendees each month. The band still played there regularly until 2010.

Following the 1999 release of the Rainmaker album, the band were approached by Kingsway with an offer of a 3 year recording contract. Bassist Danny Smith joined the band in 2001, in time for the Open album. It was at this time that the band members made the decision to leave their jobs in order to work together full time,. They also released an EP.
