James A. Long (27 August 1898 in York, Pennsylvania, USA – 19 July 1971 in California, USA) was a theosophist and president of the Theosophical Society Pasadena.
His election for president of the TS Pasadena was very controversial. As a result, some Theosophical Societies left the TS Pasadena to form the TS Point Loma-Covina.
James Long founded the theosophical journal Sunrise (magazine). He also endeavored to enlarge the Theosophical Library Center.
He was succeeded by Grace F. Knoche as president of the Theosophical Society Pasadena.
