Sir Stephen Gaselee (1762 – 26 March 1839) was a British judge, justice of the Court of Common Pleas.
He joined the western circuit, and was so much respected as a careful and well-informed junior, that when, after twenty-six years' practice, he was made a king's counsel in Hilary term 1819, his professional income was probably diminished.
Though he was not orator enough to commence practice as a leader, his deserved reputation for legal knowledge soon recommended him for a judge's place.
He was a vice-president and an active member of the Royal Humane Society, and is said to have been the original of the irascible judge represented by Dickens in the trial of Bardell v. Pickwick, under the name of Justice Stareleigh.
He resigned his judgeship at the end of Hilary term 1837, and after two years' retirement died at 13 Montague Place, Russell Square, London, on 26 March 1839.
