This day gives animal lovers the chance to celebrate one of the world's largest, most impressive carnivores. It also highlights the plight of the endangered species and encourages people to take action to save them from extinction.
To celebrate, here are 10 tracks for polar bears.
Snow (Hey Oh)
Red Hot Chili Peppers
Singer Anthony Kiedis said: "This track's about the repeated failure to start your life anew and how difficult it can be to get rid of old ways of thinking, and destructive ideas."
