In climbing, a topo (short for topology) is a graphical representation of a climbing route. Topos range from a photograph of the climb on which the line of the route is overlaid, to a detailed diagram of the key features and challenges of the climb (often represented as standardized symbols).

Climbing guidebooks compile topos for routes at a crag or in a climbing area. Online climbing databases and apps merge detailed beta (i.e. how to overcome the hardest challenges) as well as the traditional topo information. Some hand-drawn topos by the climber(s) who completed the first ascent of important new routes are notable.
