ABCD Mart is a department store in the Sesame Street Special Big Bird Gets Lost.

Big Bird and Maria go into the store to buy a pair of skates for Snuffy's birthday, and they get separated from each other. Big Bird goes to an employee, and asks for help, and tells her his number, and Granny Bird's number, and tells her that he was with Maria. She calls Maria using the intercom system, and Big Bird and Maria are happily reunited. They buy the skates and leave.

The store was never seen or mentioned again.
