Peaty is the only man to have swum the 100m under 58 seconds and also has the top 20 fastest times in history in the discipline.
The 26-year-old was pre-selected for the Games in January, along with double Olympic relay silver medallist Duncan Scott and first time Olympians James Wilby and Luke Greenbank.
Ben Proud has been included, whose trials time in the 50m freestyle would have been good for silver at the 2019 world championships, as has double Olympic silver medallist James Guy.
Brothers Joe and Max Litchfield are on the team, while 400m Individual Medley specialist Aimee Willmott is heading to her third Games.
Butterfly swimmer Alys Thomas will make her Olympic debut at the age of 30.
