The Lonsdale Cup is a Group 2 flat horse race in Great Britain open to horses aged three years or older.
It is run at York over a distance of 2 miles and 56 yards (3,270 metres), and it is scheduled to take place each year in August.
It was classed as a Listed race for several years, and it was promoted to Group 3 level in 1998.
The race was renamed the Lonsdale Cup and given Group 2 status in 2004.
The Lonsdale Cup is currently held on the third day of York's four-day Ebor Festival meeting, with the leading horses from the race often going on to compete in the following month's Doncaster Cup.
