We calculate the $W^{\pm}\gamma j+X$ production cross-sections at next-to-leading-order QCD for Tevatron and LHC collisions. We include leptonic decays of the W to light leptons, with all off-shell effects taken into account. The corrections are sizable and have significant impact on the differential distributions.
