Hardness is a specific term that refers to resistance to abrasion. The hardest substance in the human body is the enamel on our teeth. Although it is hardest to scratch, and is the last thing to wear down through erosion, anyone who's ever chipped a tooth can tell you that that thin layer of enamel isn't all that strong.
The strongest bone in terms of physical load bearing is the femur. It takes the most force in terms of pressure before it breaks.
The bones of the skull, such as the parietals, have the highest combined strength. Dense, they are more resistant to abrasion (harder) than the femur, and they are thicker and stronger than the enamel on our teeth.

I'd say your Femur. It is the hardest bone to break.

The "problem" is that human fossils are the rarest of all, and generally, only the hardest bones, jaws, teeth and skulls survive. ...

If you mean the strongest bone in the body, it is the femur, located in your thigh. As for the hardest, they all pretty much have the same "hardness".
