Duncan Huisman (born 11 November 1971 in Doornspijk, Gelderland) is a Dutch racing driver.
He is three times Dutch Touring Car Champion, having won the title in 1997, 2000 and 2001 in a BMW 3 Series.
In 2005 he first drove in the WTCC for the final two rounds with BMW Team UK, winning in what was only his second race.
Duncan drove for the WSR-managed Team Aviva in the WTCC event in Macau at the end of 2007[1] prompting speculation that he will join Team RAC in the 2008 British Touring Car Championship (BTCC) alongside Colin Turkington following the departure of Tom Onslow-Cole to Vauxhall's VXR Racing.
[2] Stephen Jelley was Onslow-Coles replacement, and Huisman returned again for just two 2008 WTCC rounds at Oschersleben for Wiechers-Sport in a BMW 320si.
