The Pacific Orthodontic Alumni Chapter is a chapter of University of the Pacific, Arthur A. Dugoni School of Dentistry's Alumni Association.

The Pacific Orthodontics Chapter's mission is to establish and maintain a mutually beneficial relationship between the Department of Orthodontics and its alumni, and to promote the science and education of orthodontics.

The Chapter serves its members by informing alumni of chapter events; hosting lectures such as the Frederick T. West Lectureship at the annual Alumni Meeting; and sponsoring the day-long graduation ceremony for the orthodontic residents, including speakers, residents' thesis presentations, reception and awards ceremony. The Chapter also publishes the alumni newsletter The Trident.
