Marcus Aefulanus was a Roman senator, who was active during the reigns of Claudius and Nero. He was suffect consul in the second half of 54.^[1] He is known to have held one other office, proconsular governor of the public province of Asia around 66/67.^[2] Aefulanus is only known from inscriptions.

Little is known about Tutor, who is the only member of the gens Aefulana to accede to the consulship, and only a little more about his gens. A Mons Aefulanus (modern Monte Sante Angelo in Arcese) is known, as well as a town of the same name on its slopes;^[3] the similar name suggests the suffect consul's family had its origins there. Less than a dozen Aefulani in total are attested, including a Marcus Aefulanus M.l. Primus, who is likely our Aefulanus' freedman or former slave.^[4] These include: one Titus Aefulanus, a local magistrate in Forum Cornelii (modern Imola);^[5] several wax tablets recovered from Pompeii mention a Publius Aefulanus Crysantus;^[6] inscriptions recovered from Augusta Emerita (near Merida, Spain) attest to four people (two freedmen) of that gens present there;^[7] and two inscriptions attest to a family of that name.^[8] Two letters of Pliny the Younger mention an Aefulanus Marcellinus.^[9] Except for the freedman Primus, there is no grounds for any of them being related to the consul.
