Blue Bayou is a full-service New Orleans/Cajun-style restaurant renowned for its unusual ambiance. Restaurants are located at Disneyland in Anaheim, California, Disneyland Paris and Tokyo Disneyland, in Chiba, Japan.

Guests wishing to dine at the restaurant are advised to make reservations at least a day in advance. At Disneyland, this is particularly true during the 4:00pm to 8:00pm dinner rush. Reservations 1 week in advance are advisable, but are able to be made up to two months in advance for the entire dining period.

The restaurant is built within the same show building that houses part of the Pirates of the Caribbean attraction, with parts of the ride even taking place beneath the restaurant. Although seated in a large, enclosed building, diners experience the illusion of eating in an outdoor restaurant at nighttime. This effect is achieved through the use of a dark and distant ceiling, air conditioning, and carefully coordinated lighting. The theming is intensified by the sounds of crickets and frogs, the meandering glow of fireflies, and projection effects above that imitate the night sky. The restaurant is also popular for offering a view of the beginning portion of Pirates of the Caribbean. Guests can see the riders floating by in their boats, and the riders can see the festive nighttime lighting of the restaurant as they pass by. Riders have been known to tease diners by shouting "don't eat the fish!" as they float by the restaurant.
