Begonia sutherlandii, known as the Sutherland begonia and as iwozya in Kimalila, Tanzania, is a tuberous flowering perennial plant in the family Begoniaceae, growing to 0.5 metres with fleshy pink stems from 10 to 80 centimetres long.
Begonia sutherlandii is native to the southern highlands of Tanzania and is often found hanging over rocks in damp shady situations or on trees. It is also present in the Democratic Republic of the Congo and in South Africa. The leaves of the plant are commonly dark green and veined with red and covered with short hairs on the underside. They are asymmetrical in shape and the margin is toothed. Flowers, produced in pendent panicles throughout summer, are 20–26 millimetres (0.8–1.0 in) in diameter, and are usually orange or orange–red with yellow anthers.
