The following is a list of regions on Mars given the name Terra (pl. Terrae). Most cover large, rugged areas, often including outflow channels, cratering, and "chaos terrain". They may be contrasted with the Planitia (e.g., Amazonis Planitia) and Mare (e.g., Mare Erythraeum), smoother regions of differing albedo.
