Robert Torrens (1775 – 1856) was an Irish judge. He enjoyed, on the whole, a high reputation for impartiality and decency. While his critics called him "the notorious hanging Judge Torrens", the legal profession as a whole praised his legal ability and integrity. Despite increasing complaints about his physical infirmity, he remained on the Bench into extreme old age. Through his daughter Henrietta he was the ancestor of the Barons O'Neill.
