More than 49,000 images are entered into Wildlife Photographer of the Year every year, but our panel of judges can only award 100 winners.
Each year the Natural History Museum chooses an additional 25 of the best images from the latest competition shortlist. We then ask the public to help us select the recipient of the People's Choice Award.
Look through the gallery above to find your favourite image, then enter your details and submit your vote. Voting closes at 14.00 GMT on 2 February 2021.
Remember: you only have one vote, so choose carefully.
Please read the terms and conditions before voting.
You can see all the shortlisted images on display in the Wildlife Photographer of the Year exhibition at the Natural History Museum in London until 6 June 2021.
