Tree63 is a Christian rock band from Durban, South Africa.
The band was formed in 1996 and originally, it was unnamed. In 1997, the band had to come up with a name before performing at North Beach, Durban. So John Ellis, the group's founder, came up with the name Tree because he was standing under one. They added the 63 in 2000 due to a naming conflict with an American band.63 had been the name of their second album, which was named in reference to Psalm 63.
