John W. Kawaja (born April 27, 1961[citation needed] in Chandler, Quebec) is a Canadian curler.

Kawaja moved to Ontario as a youth, and became a high-profile skip (he won the 1980 Ontario junior championship), but it was not until his move to the Ed Werenich rink that he finally started to win championships.

In 1984, the team repeated their provincial championship, but lost in the Brier final to Michael Riley's Manitoba rink.

Kawaja was promoted to the third position for Werenich, and in 1990 won his third provincial title.

Kawaja was named to the Canadian Curling Hall of Fame in 1991.
