# annotation

An **annotation** is a defined location on a map in the [Mapbox Maps SDK for iOS](https://docs.mapbox.com/ios/maps/) that is represented by a custom [`UIView`](https://developer.apple.com/documentation/uikit/uiview) or [`UIImage`](https://developer.apple.com/documentation/uikit/uiimage).

You can use annotations to represent point data, such as restaurants in a city, bus stops along a route, or earthquake locations. There are multiple ways to add annotations to your maps in the Mapbox Maps SDK for iOS. These methods are outlined in the [Mapbox Maps SDK for iOS documentation](https://docs.mapbox.com/ios/maps/guides/annotations/).
