Glasson Court Park is a 2.9-acre park located in the Windy Arbour area of Dundrum, Dublin. It is situated on the banks of the River Slang, a tributary of the River Dodder. According to some accounts the park is named after Glasson Court, a housing estate that was built on the site in the 1960s. However it is more likely that Glasson Court Park is named after the local village of Windy Arbour, which was historically called Glassons. The name Glassons is derived from the Irish word , meaning "the green land."

The name Windy Arbour or Sandy Arbour was later applied to the area, referring to a landing-point on the River Slang. A starch mill was formerly located there. “Arbour” once had the meaning “grass plot, lawn, garden”; it is possible that the name was intended as a direct translation of glasáin. So, the name Glasson Court Park is likely a reference to both the historical name of the area and the local village.
