The femur is your thigh bone, running from your hip to your knee.

Quick Scoop: Where it is

  • It’s the single long bone in the upper part of your leg, between the hip joint and the knee joint.
  • When you sit and look at your lap, the hard bone deep inside each thigh is your femur.
  • The top of the femur forms part of your hip; the bottom widens to help form the knee joint.

A simple way to picture it: if you put your hand on the front of your upper leg and imagine a strong rod of bone from your hip to your knee, that “rod” is your femur.
