Jan Russell Schelhaas (born 11 March 1948) is an English musician, mostly known as the keyboard player from the bands Caravan and Camel.

After the recording, he left Moore to do solo projects including an organ session on Thin Lizzy's 1973 Vagabonds of the Western World album.

In July 1975, Schelhaas was asked to play keyboards in the band Caravan after Dave Sinclair left them.

Jan Schelhaas toured around the world with the band and recorded three albums: Blind Dog at St. Dunstans (1976), Better by Far (1977) and Cool Water, which was not released until 1994.

In 1978, Caravan had a break and Schelhaas accepted an offer to join Camel on their world tour for their album Breathless (1978).
