Chimay (French pronunciation: [ʃimɛ] ⓘ, Walloon: Chimai) is a city and municipality of Wallonia located in the province of Hainaut, Belgium.

The Trappist monastery of Scourmont Abbey in the town is famous for the Chimay Brewery.

The etymology of the name is ultimately, via Vulgar Latin, from the Proto-Celtic word koimos meaning "pretty, pleasant".

Chimay has traditionally hosted an annual motor racing event, run on a street circuit formed from local public roads.

The track briefly lost its licence in 2006 related to safety fears, but has since had it reinstated.
