Trinity Episcopal Church has a long history involving its organs. The first organ listed as having been installed in this church was an 1850's Henry Erben instrument of unknown specification. Shortly thereafter, a Jardine and Son organ was installed. That instrument is listed as having 1 manual and 8 stops. The next organ upgrade occurred in 1880 with the installation of a JH & CS O'Dell organ (Opus 239) which had 3 manuals and 4 divisions. In or around 1910, Austin installed their Opus 536, which was also a 3 manual instrument containing 32 stops. In the 1950's Austin upgraded the organ and added two additional ranks. In the 1970's Rive Organ Company added additional stops bringing the count up to 40 stops on 36 ranks. In the 1990's Roy Redman installed his Opus 56 which was a 4 manual tracker instrument of 80 ranks. That is the present instrument in the main sanctuary.

The original chapel organ was Moller Opus 3847, installed in the 1920's. That organ was then sold to a parishoner of Mount Olivet Episcopal Church on Algiers Point, and the parishoner donated it to Mount Olivet and had it installed in their building. In the 1930's, Trinity purchased a somewhat larger instrument, Moller OPUS 8257. That is the present instrument.
