Morton's neuroma (also known as Morton's metatarsalgia, Morton's neuralgia, plantar neuroma and intermetatarsal neuroma) is a benign neuroma of an intermetatarsal plantar nerve, most commonly of the third and fourth intermetatarsal spaces.

This problem is characterised by pain and/or numbness, sometimes relieved by removing footwear.

Despite the name, the condition was first correctly described by a chiropodist named Durlacher, and although it is labeled a "neuroma", many sources do not consider it a true tumor, but rather a perineural fibroma (fibrous tissue formation around nerve tissue).

Symptoms include: pain on weight bearing, frequently after only a short time. The nature of the pain varies widely among individuals. Some people experience shooting pain affecting the contiguous halves of two toes. Others describe a feeling like having a pebble in their shoe. Burning, numbness, and paresthesia may also be experienced.

Morton's neuroma lesions have been found using MRI in patients without symptoms.
