superficial fibular nerve

Both muscles are innervated by the superficial fibular nerve.

The lateral compartment of the leg is supplied by the superficial fibular nerve.

Superficial fibular nerve (yellow) - labeled as "superficial peroneal nerve".

It is innervated by the deep fibular nerve, unlike the other peroneal muscles which are innervated by the superficial fibular nerve, since the peroneus tertius is a member of the anterior compartment.
