James Tyrrell (5 May 1642 – 17 June 1718) was an English author, Whig political philosopher, and historian.
When Pierre Des Maizeaux set about compiling A Collection of Several Pieces of Mr. John Locke, a posthumous edition of lesser-known works and manuscripts, he recorded his conversations with Tyrrell who spoke at some length about his friend.
According to a memorial to him, "He was a man of rare integrity, gravity, and wisdom: had never polished himself out of his sincerity: nor refined his behaviour to the prejudice of his virtue.
He was a warm and zealous lover of his country, & of that system of religion and law which he well knew could only support it."
