The Lowther Stakes is a Group 2 flat horse race in Great Britain open to two-year-old fillies.
It is run at York over a distance of 6 furlongs (1,207 metres), and it is scheduled to take place each year in August.
A different event called the Lowther Stakes, a middle-distance race open to horses aged three or older, used to be contested at Newmarket.
The present version is named in memory of Hugh Lowther (1857–1944), the 5th Earl of Lonsdale.
The Lowther Stakes is currently held on the second day of York's four-day Ebor Festival meeting.
