Mail for Harriet

If you would like to send a letter in the post to Harriet, you are welcome to use the address below. However, please consider saving the environment (and postage cost!) by sending a photograph of the letter over social media. If you do send a physical letter, it’s very helpful if you can please include a stamped, self-addressed envelope for Harriet’s reply.

While Harriet absolutely loves hearing from people who have enjoyed her books, please do not send Harriet any of your or your child’s own stories. Harriet is constantly working on new ideas for her own stories, and there could be issues caused if one of Harriet’s future stories happens to appear similar to an unpublished story she has been sent.

Postal address:

Harriet Muncaster
c/o  Children’s Publicity Team
Oxford University Press
Great Clarendon Street
United Kingdom

Harriet reads every letter and aims to respond to as many as she can as quickly as possible, but due to her busy schedule this can take several months!
