From Harry Potter, to Willy Wonka – from Mary Poppins to Gangsta Granny, amazing costumes are on show every year.
Children across Derbyshire are to set to go school dressed as their favourite book characters for the annual event on Thursday, March 5.
The day is an annual charity event held on the first Thursday of March every year to provide every child in full-time education with a voucher to be spent on a book of their choosing.
World Book Day aims to encourage reading for pleasure amongst children and is promoted in more than 100 countries around the globe.
Schools often ask both pupils and teachers dress as their favourite book characters.
We have taken a look back at some amazing outfits - and we look forward to seeing all of your new costumes next month!
