Irish Bayou

Irish Bayou is a community along a body of water of the same name within the legal boundaries of the city of New Orleans, Louisiana, but separated from the rest of the city by undeveloped wetlands. It falls within a group of communities collectively known as Eastern New Orleans. It is located at latitude 30°08'30", longitude 89°51'50", with an average elevation of 1 meter. It is primarily a sport fishing community with few permanent residents.

The Irish Bayou Castle, also known as Fisherman's Castle, was built in 1981 in preparation for the 1984 Louisiana world exposition. The castle is now owned and used by Charles and Jean Khul as a hunting and fishing camp.

The origin of the community of Irish Bayou is obscure.
