A pony of Tom Bombadil's. Tom rarely rode Fatty Lumpkin, also known as "Lumpkin," who spent most of his time free-ranging on the Barrow-downs.
Tom did spend some time riding on Fatty Lumpkin with Frodo and his friends after their run-in with a Barrow-wight.
The fact that Fatty Lumpkin was noted as being fatter than Frodo and his companions' ponies is probably where his name came from. The pony's full name, which ends in the diminutive -kin, is something along the lines of "fat little lump."
The strong bond that the Hobbits' ponies had formed with Lumpkin while staying at Tom's home is what brought them back to Tom Bombadil after they made it out of Bree.
