The fibularis muscles (also peronæus) are a group of three muscles fibularis (peronæus) longus, brevis, and tertius originating on the fibula and inserting on the metatarsals.
The "longus" and "brevis" are much more similar to each other than they are to the "tertius", as shown in the table below.
| Name | Compartment | Action | Nerve | Artery |
| Fibularis longus | lateral compartment | eversion and plantarflexion | superficial fibular nerve | fibular artery |
| Fibularis brevis | lateral compartment | eversion and plantarflexion | superficial fibular nerve | fibular artery |
| Fibularis tertius | anterior compartment | eversion and dorsiflexion | deep fibular nerve | anterior tibial artery |
The peroneus muscles are highly variable and several variants have been noted as being occasionally present, such as peroneus digiti minimi and peroneus quartus.[1] The quartus is more closely associated with the tendons of the extensor digitorum longus, and may send a small tendon to the fifth digit[2] (assumably described as the digiti minimi above).
