1921–22 Plunket Shield season

The 1921–22 Plunket Shield season was a tournament of the Plunket Shield, the domestic first-class cricket competition of New Zealand.

Auckland won the championship. For the first time, the Shield was not contested on the basis of challenge matches but by a single round-robin tournament between four first-class sides, Auckland, Canterbury, Otago and Wellington. Hawke's Bay, which had had first-class status and had challenged Auckland for the Plunket Shield in 1920-21, did not compete.

Raoul Garrard, the Auckland leg-spinner, took the most wickets, 23 at an average of 10.34, and had the best figures, 8 for 51 against Canterbury.
