KCB Rugby Club is a rugby union team based in Nairobi, Kenya. It was formed in 1989 after the disbanding of Kenya Breweries RFC when their main sponsor, Kenya Breweries, pulled out. That year they joined the Kenya Cup. Their first match was against Impala RFC, whom they beat 96–6. In 1994 the team was relegated to the Eric Shirley Shield, however by 1996 they had regained their position in Kenya's top rugby league. The club now has a 2nd XV team which has performed well, winning the Mwamba Cup, and Eric Shirley Shield several times.
