Josphat Kiprono Menjo (born 20 August 1979) is a Kenyan long-distance runner who specialises in track and road running. A relative latecomer to athletics, Menjo began competing around 2002 and first represented his country at the 2006 African Championships in Athletics, where he was fifth in the 5000 metres. A silver medal in the event at the 2007 All-Africa Games was followed by an eighth-place finish on the global stage, running in the 10,000 metres at the 2007 World Championships in Athletics. He won the San Silvestre Vallecana 10K race at the end of the year.
