Derek Leslie Quinnell (born 22 May 1949) is a Welsh former rugby union player.
Quinnell made his international debuts for the Lions against New Zealand in 1971 and for Wales against France in 1972.

His three sons, Scott, Craig and Gavin went on to play top-flight professional rugby, with Craig winning caps for Wales in rugby union and Scott earning Wales caps in both union and league.
Derek's youngest son, Gavin, played professionally for the Magners League side Scarlets before an injury suffered in an October 2010 match between Llanelli RFC and Cross Keys cost him the sight in his left eye.
