Helen Tracy Lowe-Porter (June 15, 1876/1877, Towanda, Pennsylvania – died April 26, 1963, Princeton, New Jersey) was an American translator, most well known for her pioneering translations of the works of Thomas Mann.

Helen Tracy Porter was the daughter of Clara (née Holcombe) and Henry Clinton Porter. She was the niece of Charlotte Endymion Porter, editor of Poet Lore, a poetry journal, and an expert on Shakespeare and Elizabeth and Robert Browning.[4] She married the paleographer Elias Avery Lowe in 1911 and took the married name of Lowe-Porter. The couple lived in Oxford; after 1937, their residence was in Princeton, New Jersey. One of their daughters, Frances, was the maternal grandmother of London mayor Boris Johnson. For more than two decades, Lowe-Porter enjoyed exclusive rights to translate the works of Thomas Mann from German into English. She was granted these rights in 1925 by Alfred A. Knopf.
