John Kenneth George Hastie (6 September 1928 – 2 October 2002) was a South African footballer who played as a centre forward.
On 17 September 1952, Hastie made his debut for Leeds against Birmingham City in a Second Division game, scoring twice in a 2–2 draw.
Hastie only made three more league appearances for the club, due, in part, to the emergence of John Charles.
At the end of the 1952–53 season, Hastie was released by Leeds, returning to South Africa to play for Germiston Callies.
