Cyrus Gichobi Njui (born 11 February 1986) is a Kenyan long-distance runner who specialises in road running competitions.

Njui initially competed in the steeplechase and the 10,000 metres. He moved to Japan at a young age and studied at Ryutsu Keizai University. In 2006 he won the Sapporo Half Marathon (running for Nissan Motors) and was part of the winning Kenyan team at the International Chiba Ekiden.
