Châteauguay-Laprairie was a former provincial electoral district in the province of Quebec, Canada.
Many sources (including the National Assembly website) write it as Châteauguay-La Prairie, but contemporary sources show the "Laprairie" part of the name written as one word. This alternate way of spelling it is probably by analogy with the modern-day La Prairie electoral district, which was spelled "Laprairie" before 1988.[1]
It was created for the 1939 election, from parts of the Châteauguay and Napierville-Laprairie electoral districts. It existed for only that one election. It disappeared in the 1944 election and its successor electoral district was the recreated Châteauguay.
