Pitcairn Islanders, also referred to as Pitkerners and Pitcairnese, are the native inhabitants of the Pitcairn Islands, a British Overseas Territory including people whose families were previously inhabitants and maintaining cultural connections. Most Pitcairn Islanders are descendants of the Bounty mutineers.

The descendants of the Bounty mutineers include the modern-day Pitcairn Islanders as well as a little less than half of the population of Norfolk Island. Their common ancestors were the nine surviving mutineers from the mutiny on HMS Bounty which occurred in the south Pacific Ocean in 1789. Their descendants also live in New Zealand, Australia, and the United States.
