In loop quantum gravity, the boundary term at a black hole horizon is formally equivalent to an action for three-dimensional gravity. I show how to use this equivalence to obtain the four-dimensional Bekenstein-Hawking entropy from well-understood computations of the entropy of the three-dimensional black hole.
