Abstract
We classify fibred closed 3-braids. In particular, given a nontrivial closed 3-braid, either it is fibred, or it differs from a fibred link by adding a crossing. The proof uses Gabai's method of disk decomposition. The topmost term in the knot Floer homology of closed 3-braids is also computed.
