Ian Douglas Turner (born 10 October 1949) is a former motorcycle speedway rider from England.
On 14 July 1971, Turner won the British Speedway Under 21 Championship, held at the Abbey Stadium in Swindon. While riding for King's Lynn in 1973 he broke his arm in a crash.
Turner reached the final of the British Speedway Championship in 1979. He rode in the top tier of British Speedway from 1969 to 1980, riding primarily for King's Lynn Stars.
He retired in 1980 but was tempted back to ride a few matches for Boston Barracudas by promoter, Cyril Crane. Ian appeared in about 12 meetings, with a final appearance against Mildenhall Fen Tigers when he scored maximum points from five rides.
Post speedway, Ian drove lorries for a living and rode a Harley for a hobby. He has lived in Spalding since 1971.
