The Metatemporal Detective is a collection of short fiction by British fantasy and literary writer Michael Moorcock .

The stories chart the adventures of the Holmesian detective Sir Seaton Begg, his trusty sidekick Dr. Taffy Sinclair and his complex relationship with his cousin, nemesis, and occasional ally, Monsieur Zenith. The stories are set in an eclectic range of times and places and were written over the course of Moorcock's long career. The book features characters from the Moorcock 'multiverse' including the ubiquitous Una Persson. Begg owes much to the character of Sexton Blake, the Publishers Weekly termed the stories rather too 'broad' in their parody of established detective tropes . The stories were not, according to Moorcock, designed as literary parody.

Begg makes other appearances in Moorcock's work, most recently in Zenith Lives! and The Immortal Seaton Begg, both from Obverse Books.
