Priscilla Victoria Hastings (née Bullock, 28 February 1920 – 12 August 2010) was a British racehorse owner and trainer.
She was one of the first three women to be elected as a member of the Jockey Club in December 1977, alongside her half-sister Ruth Wood (née Primrose), Countess of Halifax and Helen Johnson Houghton.
Priscilla Hastings herself owned racehorses and was part-owner (with Cath Walwynm, wife of trainer Fulke Walwyn) of the horse Taxidermist, winner of the 1958 Hennessy Cognac Gold Cup.
(His estate became involved in a lawsuit with the Inland Revenue which gave rise to a doctrine known as the "rule in Hastings-Bass" that allowed parties to declare decision void if they had results other than those originally intended.)
On the day of her death, the horse Cool Strike carried her black and yellow racing colours to third place at Newbury Racecourse.
