Is there a place to download 3d figures?

Im not so good at 3d sculpting, but I would like to practice some animation, is there a place to get models to practice rigging and animating? I know a lot of programs come with tutorials that include basic models but I learn much better if I watch how to do it and figure it out for myself on a different model...

Thank you in advance!

Here are some sites providing free resources:
