List of geological features on Titan
This is a list of named geological features on Saturn's moon Titan. Official names for these features have only been announced very recently, as Titan's surface was virtually unknown before the arrival of the Cassini–Huygens probe. Some features were known by informal nicknames beforehand; these names are noted where appropriate. Note that some features with a physical size given by "diameter" may not be circular and actually refers to its length.

Informal names for previously unnamed features
Because the exact nature of many surface features remain mysterious, a number of features took time to receive formal names and are known by nicknames. In most cases, indications of brightness and darkness refer not to visible light, but to the infrared images used to look through Titan's obscuring haze.- 'The Sickle': a large, dark, sickle-shaped region identified by the Hubble Space Telescope.
- 'Throat of Kraken': unofficial name for the strait that separates the north and south basins of Kraken Mare, before officially being named Seldon Fretum. It was used in early publications that hypothesized about its role with tidal dissipation and surface currents between the two basins of Kraken Mare.
