'Aberlour' was a British unrealised plan for an attack on the German salient to the north of Caen in Normandy for implementation in the event that 'Epsom' proved successful (late June 1944).

The operation was schemed as a follow-on to 'Mitten' and in parallel with 'Ottawa' and, had it taken place, Major General L. G. Whistler’s 3^rd Division (with Brigadier D. C. Cunningham’s Canadian 9^th Brigade under command) would have attacked the area held by Generalleutnant Erich Diester’s 346^th Division and Generalleutnant Edgar Feuchtinger’s 21^st Panzerdivision of General Hans von Obstfelder’s LXXXVI Corps within General Geyr von Schweppenburg’s Panzergruppe 'West' to take several villages to the north of Caen.

'Epsom' was a failure, however, and Lieutenant General J. T. Crocker’s I Corps therefore cancelled 'Aberlour' on 28 June.
