The Birthday Ghost is a ghost of a woman standing at the far left of the dining table in the Ballrooms of Disneyland, Walt Disney World, and Tokyo Disneyland. She can be seen standing on a chair and blowing out the 13 candles on a birthday cake. At Disneyland and Tokyo Disneyland, she remains visible, but at Walt Disney World, she disappears along the other ghosts around the table. A 1970s standard operating procedure manual for the Disneyland attraction refers to her as the "Ghostess," who has invited her friends of the spirit world to dance, play, and share her birthday cake. Another "Ghostess" beckons visitors to hurry back at the end of the attraction.
She has auburn hair and wears a pink gown in the ride, but in the comics, she has light blue hair and wears a blue dress. She wears a birthday hat.
- At Disneyland Paris, she is replaced with the ghost of a woman who is toasting with a wine glass.
- The Birthday Ghost has the same face as the horn player in the Graveyard band.
