Abstract: We analyze the level-rank duality of untwisted and epsilon-twisted D-branesof the soN K WZW model. Untwisted D-branes of soN K are characterized byintegrable tensor and spinor representations of soN K. Level-rank dualitymaps untwisted soN K D-branes corresponding to equivalence classes oftensor representations onto those of soK N. The epsilon-twisted D-branes ofso2n 2k are characterized by a subset of integrable tensor and spinorrepresentations of so2n-1 2k+1. Level-rank duality maps spinorepsilon-twisted so2n 2k D-branes onto those of so2k 2n. For both untwistedand epsilon-twisted D-branes, we prove that the spectrum of an open stringending on these D-branes is isomorphic to the spectrum of an open string endingon the level-rank-dual D-branes.
