Johan Wilhelm Zulch (2 January 1886 – 19 May 1924) was a South African international cricketer who played 16 Test matches for South Africa between 1910 and 1921.

His cricket career was interrupted by World War I, but he still managed 985 Test runs at an average of 32.83, with two Test centuries — both against Australia on his first overseas tour in 1910–11.

Zulch batted for three hours, and a hundred from Tip Snooke then boosted South Africa to 482; and, despite 214 from Australian batsman Victor Trumper, and a relative failure from Zulch with 14 in the second innings, South Africa went on to win by 38 runs.

In the 2nd Test (1921) against Australia at Old Wanderers in Johannesburg, Australian fast bowler Ted McDonald dismissed Zulch by breaking his bat so that fragments flew back to dislodge a bail, and the Zulch was given out, "hit wicket".
