Jared Bradley Flagg (June 16, 1820 – September 25, 1899) was an American painter from New Haven, Connecticut. He was the younger brother of artists George Whiting Flagg and Henry Collins Flagg III. His father, Henry Collins Flagg, was a one time mayor of New Haven.
The Flagg brothers all studied painting under their famous uncle, Washington Allston, and received some recognition of their own. When he was only sixteen years old, Jared exhibited a portrait of his father in the National Academy and was favorably noticed by the critics.
As a young man, Flagg settled in Hartford, Connecticut. However, he moved to New York in 1849 and was soon elected an academician. Jared pursued the study of theology at intervals with his art, and, in 1854, he entered the ministry of the Protestant Episcopal Church. Among his seven children was Ernest Flagg, who became a notable architect.
Jared received the degree of A.M. from Trinity College in 1861, and that of S.T.D. from Columbia in 1863. For ten years he devoted himself to the discharge of his theological duties, then he returned to the practice of his art.
Flagg occasionally painted ideal figure pictures but made portraits his specialty. Among Flagg's more notable portraits are of several of the judges of the New York Court of Appeals, including a three-quarter length of Chief Justice Sanford E. Church, which was placed in the new state capitol; a life-size full-length of William M. Evarts, also hung in the capitol (1887); and several portraits of Commodore Vanderbilt, one of which hangs in the directors' room at the Grand Central depot in New York. Other notable paintings by Jared Flagg include Holy Thoughts and Paul before Felix (1849), and Angelo and Isabella (1850).
