All Souls College (official name: The College of All Souls of the Faithful Departed, of Oxford) is a constituent college of the University of Oxford in England. Unique to All Souls, all of its members automatically become fellows (i.e., full members of the college's governing body). It has no student members, but each year, recent graduates are eligible to apply for a small number of examination fellowships through a competitive examination (once described as "the hardest exam in the world") and, for those shortlisted after the examinations, an interview.

The college entrance is on the north side of High Street, whilst it has a long frontage onto Radcliffe Square. To its east is The Queen's College, whilst Hertford College is to the north of All Souls.

The current warden (head of the college) is Sir John Vickers, a graduate of Oriel College, Oxford.
