Disambiguation: Aerial Phenomena Research Organization (APRO) is the civilian UFO research group founded by Jim and Coral Lorenzen (1952–1988), distinct from the U.S. Air Force's Project Blue Book (military) and NICAP (civilian but separate organization).

The Aerial Phenomena Research Organization (APRO) was a civilian UFO research group founded in January 1952 by Jim and Coral Lorenzen in Sturgeon Bay, Wisconsin, and relocated to Tucson, Arizona by 1960. APRO conducted systematic field investigations into unidentified flying objects and maintained a roster of PhD-level consulting scientists, including atmospheric physicist James E. McDonald and UC Berkeley engineer James Harder. The organization published the APRO Bulletin bimonthly, achieved peak membership of 1,500 in 1967, and was cited by astronomer J. Allen Hynek as one of the two best civilian UFO research groups of its era. APRO experienced a major schism in 1969 when Walt Andrus departed to form the Midwest UFO Network (later the Mutual UFO Network), contributing to membership decline. Jim Lorenzen died in 1986 and Coral in 1988; the board voted to disband APRO shortly thereafter, ending the organization's 36-year run in late 1988. APRO's archived case files—numbering in the tens of thousands—were transferred to the National UFO Historical Records Center in 2023.

A Organização de Pesquisa de Fenômenos Aéreos (APRO, sigla em inglês) foi um grupo civil de pesquisa em UFOs fundado em janeiro de 1952 por Jim e Coral Lorenzen em Sturgeon Bay, Wisconsin, e realocado para Tucson, Arizona até 1960. A APRO conduzia investigações sistemáticas de campo sobre objetos voadores não identificados e mantinha um quadro de cientistas consultores com doutorado, incluindo o físico atmosférico James E. McDonald e o engenheiro da UC Berkeley James Harder. A organização publicou o Boletim APRO bimensalmente, atingiu pico de 1.500 membros em 1967, e foi citada pelo astrônomo J. Allen Hynek como um dos dois melhores grupos civis de pesquisa em UFOs de sua época. A APRO sofreu um grande cisma em 1969 quando Walt Andrus saiu para fundar a Midwest UFO Network (depois Mutual UFO Network), contribuindo para o declínio de associados. Jim Lorenzen morreu em 1986 e Coral em 1988; o conselho votou para desativar a APRO pouco depois, encerrando a trajetória de 36 anos da organização no final de 1988. Os arquivos de casos da APRO—totalizando dezenas de milhares—foram transferidos para o Centro Nacional de Registros Históricos de UFOs em 2023.
