The Tinkerer, real name Phineas Mason and sometimes known as the Terrible Tinkerer, is a fictional character, a supervillain appearing in comic books set in Marvel Comics. The character has an almost superhuman gift of genius in engineering, able to invent sophisticated gadgets from nothing more than spare parts left over from ordinary household appliances.

Phineas Mason is a brilliant inventor and technician who designs advanced weaponry for criminals and sometimes undertakes crimes of his own. As the "Terrible Tinkerer", he runs an underground fix-it shop disguised as a radio repair shop. On at least one occasion, a potential customer gained the inventor's attention by presenting a transistor radio and telling Mason that "I've got a radio that just can't carry a tune". Tinkerer's original scheme involved the employment of a team of petty has-been stuntmen and thugs. They specialized in placing bugs into radios and blackmailing state officials and politicians.
