The Thing is Big Ben was a weekly comic published by Marvel UK from 28th March 1984 to 25th July 1984 (18 issues). It featured reprints from the American Marvel Comics title Marvel Two-in-One, starring Ben Grimm, alias The Thing of the Fantastic Four (hence the title, which attempted to put a British spin on the character by linking him somewhat obscurely with the famous bell of the Westminster clock tower) as well as back-up strips featuring Iron Man and Captain America. After the title's cancellation, its lead strip was transferred to the pages of Spider-Man weekly.

The first two issues carried cover mounted free gifts; a thin card Big Ben cap in the first and a cardboard "Big Ben Banger" in the second.
