Derek Ringer (born 11 October 1956) is a Scottish rally co-driver. He is most closely associated with Colin McRae, with whom he won the 1995 World Rally Championship.

Although their partnership extended back to the 1980s when McRae was a teenager, the two split at the end of 1996 when they failed to defend their title, several mid-season crashes being blamed on Ringer. After a year's absence, Ringer returned to partner Martin Rowe in the British Rally Championship, the pair winning the 1998 title in a Renault Mégane Maxi and competing together in the World Rally Championship in 1999.
