Lake Selfe, or Te Ruahikihiki in Māori, is a lake in the Selwyn District of the Canterbury Region in the South Island of New Zealand.
Lake Selfe is situated in the Selwyn District between the Cottons Sheep Range, which reaches heights of up to 1,470 m (4,820 ft) to the south and west, and Mount Ida, which rises to 1,695 m (5,561 ft) to the north-northeast, as well as Little Mount Ida, which rises to 1,050 m (3,440 ft) to the east. The 64.3 ha (159-acre) lake stretches at an elevation of 574 m (1,883 ft) and is approximately 2.09 km (1.30 mi) long in a northwest–southeast direction. At its widest point, it measures approximately 540 m (1,770 ft) in a southwest–northeast direction. The lake's circumference is approximately 4.77 km (2.96 mi).
Lake Selfe is fed by a few streams and has its outflow—Moss Burn—at the northwest end of the lake. Its waters flow via Lake Henrietta into the Harper River.
The original Māori name of the lake is Te Ruahikihiki. The European name given to the lake was for Henry Selfe, a member of the Canterbury Association.
