What's My Letter? is a Sesame Street electronic learning game made in 1995 by Fisher-Price. The game is inspired by the Sesame sketch "What's My Letter?"

Host Guy Smiley and the three contestants -- Elmo, Big Bird and Zoe -- are all heard in pre-recorded voice clips. Games are chosen by placing a card in the slot in front of the contestants. To choose a letter, the player turns the dial on the front of the game to move the light in the marquee to the appropriate letter.

Games teach letter identification, alphabetical order and beginning letters.
