Participating nations A total of 24 countries entered competitors to compete in swimming.

Argentina (4) Australia (38) Bermuda (3) Bolivia (1) Brazil (11) Canada (44) China (12) Chinese Taipei (5) Colombia (1) Eritrea (1) Germany (2) Guatemala (1) Italy (2) Jamaica (4) Japan (37) Mexico (9) Micronesia (1) New Zealand (17) Palau (1) Peru (1) Philippines (4) Singapore (3) South Africa (26) United States (60) (host)

Additionally, four European swimmers (two from Germany and two from Italy) were permitted to compete in open water events. Bolivia also entered only one competitor in men's open water.

Australian swimmers Mollie O'Callaghan and Kaylee McKeown withdrew from the championships due to health concerns; for O'Callaghan, who was managing a spinal stress fracture, it would have been her first appearance at the senior Pan Pacs, while McKeown was forced to pull out after being diagnosed with glandular fever.

Cameron McEvoy and Kyle Chalmers both chose not to participate in the Pan Pacific Championships, opting to focus on the 2026 Commonwealth Games instead.

A report by Swimming World highlighted several major omissions from the United States roster—including American record-holder Anna Moesch, Isabelle Stadden, Ryan Erisman, and Luka Mijatovic—due to USA Swimming selecting the team a year in advance based on 2025 competition times rather than holding a dedicated 2026 selection meet.
