Roger T. Pratt (born 1944) was a Welsh cyclist from Cardiff, Wales. He began road racing in 1962, winning his first event the following year. In 1965 he rode the Tour of Britain Milk Race for the Britannia team (after one of the French riders dropped out). Drug testing was introduced for the first time in this race and Pratt was tested twice. After 5 years of competition in the UK he retired from competition aged only 23, in 1967. Pratt raced again briefly in 1988 when he became Welsh Veterans Road Race Champion.
