We report the joint WASP/KELT discovery of WASP-167b/KELT-13b, a transiting hot Jupiter with a 2.02-d orbit around a V = 10.5, F1V star with [Fe/H] = 0.1 plusmn 0.1. The 1.5 R$_Jup$ planet was confirmed by Doppler tomography of the stellar line profiles during transit. We place a limit of $8 M$_Jup$ on its mass. The planet is in a retrograde orbit with a sky-projected spin-orbit angle of $ = -165deg plusmn 5deg. This is in agreement with the known tendency for orbits around hotter stars to be more likely to be misaligned. WASP-167/KELT-13 is one of the few systems where the stellar rotation period is less than the planetary orbital period. We find evidence of non-radial stellar pulsations in the host star, making it a $-Scuti or $-Dor variable. The similarity to WASP-33, a previously known hot-Jupiter host with pulsations, adds to the suggestion that close-in planets might be able to excite stellar pulsations.
