Frederick "Frank" Marchant (ca. 1872 – February 6, 1942) was an American photographer. Born in Pennsylvania, he moved to Hamlet, North Carolina to work as an engineer for the Seaboard Air Line Railroad railway before opening a photography studio in 1907. Most of his work consisted of outdoor scenes in Hamlet and the nearby city of Rockingham, selling his work on postcards. He also worked for several years as an official photographer for Seaboard and captured numerous images of trains and train wrecks. Marchant's career declined in the late 1920s and early 1930s due to his alcoholism and the Great Depression. The remaining negatives in his possession were destroyed after his death in 1942, though some of his images were preserved by the State Archives of North Carolina and in private collections.
