Lenana School is a secondary school in Nairobi, Kenya. It was formed in 1949 by colonial governor Philip Euen Mitchell, known then as the Duke of York School, named after a British World War II 1939 King George V-class battleship. The bell from HMS Duke of York is mounted on a bell-shed by the front of the school parade ground between the school chapel and the hall. The first students were briefly housed at the then-British colonial governor's house, which is the current State House as they waited for the school's completion. The founding principal was R. H. James.
