James Nitties (born 23 October 1982) is an Australian professional golfer who plays on the PGA Tour.

Nitties was born in Melbourne, Australia. He suffered from juvenile arthritis as a child and young adult, which restricted his flexibility. This caused him to have to take pain killers to restrict the pain from his back. In 2003, he finished second at the Western Amateur to Ryan Moore in 19 holes. He turned professional in 2004.

In 2004, Nitties joined the NGA Hooters Tour where he played for three years, winning once. While he played the Hooters Tour, he played a select few of events on the Nationwide Tour and the PGA Tour of Australasia.
