Jennie's Hat is a 1971 children's picture book by American author and illustrator Ezra Jack Keats.

The protagonist, a girl called Jennie is looking forward to receiving a new hat from her aunt - “It will be big and beautiful and flowery,” she tells herself happily.

She is disappointed and tries different items on her head, like a flowerpot and a kettle but they don't work.

However, on the way home Jennie's bird friends bring various items for her to decorate the hat so it isn't plain anymore.

Jennie's Hat has proved popular amongst schools and libraries and has been used for encouraging children activities.
