The Oh So Sharp Stakes is a Group 3 flat horse race in Great Britain open to two-year-old fillies.
It is run on the Rowley Mile at Newmarket over a distance of 7 furlongs (1,408 metres), and it is scheduled to take place each year in October.
The event is named after Oh So Sharp, a Newmarket-trained winner of the fillies' Triple Crown in 1985.
The race was previously held on the second day of Newmarket's three-day Cambridgeshire Meeting, the day before the Cambridgeshire Handicap, but was moved to a fixture a week later in 2014.
From 2015 it was moved back a further week to become part of the Future Champions Festival at Newmarket.
