This is an oak-apple gall. Here's a link to more information:

Unless you have hundreds of them, they aren't a problem for the tree.
If you'd like more information, please feel free to call me. Thanks for contacting Cooperative Extension!

Ok. Thanks so much!!!

Oak gall are created by a wasp and rarely harms the tree.
