Greenhalgh Castle is a castle, now ruined, near the town of Garstang in Lancashire, England.
Thomas Stanley, 1st Earl of Derby, had the castle built in 1490 to provide defence for his estates around Garstang. He was also allowed to enclose a park and have in it 'free warren and chase'. The land on which the castle was built is said to be a gift to Stanley from his stepson Henry Tudor for his assistance in defeating Richard III at the Battle of Bosworth.
