Phelps, who is returning from retirement, made the team in the (100-meter freestyle, 100 backstroke, 100 butterfly and 200 individual medley.
He's joined by Chase Kalisz (200 fly, 200 IM, 400 IM); Conor Dwyer (200 free, 200 IM); Matt McLean (200 free, 400 free); Allison Schmitt (200 free); Cierra Runge (400 free, 800 free); and Becca Mann (400 free, 800 free, 400 IM, open water 10K).
The team is headlined by Phelps, of Baltimore, and fellow world-record holders Missy Franklin (Centennial, Colo.), Katie Ledecky (Bethesda) and Ryan Lochte (Daytona Beach, Fla.).
"The USA Swimming National Team represents the pinnacle of competitive swimming in the United States," said Frank Busch, USA Swimming national team director. "This group of dedicated and talented athletes will positively represent our country and continue to build on our tremendous legacy of success in and out of the pool."
Phelps, who led the U.S. men with five medals at Pan Pacific Championships last month, returns to the national team after a one-year hiatus.
Fresh off winning three medals at last month's 2014 Pan Pacific Championships, Lochte qualified for the National Team in a team-best five events — 100 free, 200 free, 200 back, 100 fly and 200 IM.
Franklin earned national team status in four events – 100 free, 200 free, 100 back and 200 back.
Ledecky, who won five gold medals and set two world records at 2014 Pan Pacs, earned a national team roster spot with top performances in the 200, 400 and 800 freestyle events.
Swimmers were selected for the national team based on their times in Olympic events from the combined results of the 2014 Phillips 66 National Championships and the 2014 Pan Pacific Championships. The top six athletes in each event made the national team, but relay leadoffs and time trials were not included.
Open water National Team members qualified with a top-six finish in the 10-kilometer race at the 2014 USA Swimming Open Water national championships.
