Nerve may refer to more than one thing:
- Nerves are part of the nervous system.
- In mathematics, a nerve refers to an abstract simplicial complex formed from a family of objects by taking intersections: the 0-simplices are the objects themselves, the 1-simplices join pairs of objects with non-empty intersections, the 2-simplices join triples of objects with non-empty intersections etc. See nerve of an open covering.
- Nerve can also refer to a cocky form of self-confidence. For example, "He has a lot of nerve coming to his ex-wife's wedding!" In American English, this use of nerve is synonymous with balls, and in Spanglish (Spanish-influenced English) cojones may be used.
- Nerve is also the name of a website-based journal distributing art (mostly fiction and photography) which is only slightly pornographic.
