Ramogi Achieng Oneko (1920–2007) was a Kenyan freedom fighter and a politician. In Kenya, he is considered as a national hero.
Oneko was one of the six freedom fighters arrested by the British colonial government in Kapenguria in 1952. Other members of the group, known as "Kapenguria Six" were Jomo Kenyatta, Paul Ngei, Bildad Kaggia, Kungu Karumba and Fred Kubai. They were arrested for allegedly being linked with the Mau Mau rebellion movement. They were released nine years later, in 1961, two years before Kenya gained independence.
The first parliamentary election were held on independence in 1963 and Achieng Oneko won the Nakuru Town Constituency seat. Jomo Kenyatta became the first president of Kenya and soon appointed Achieng Oneko Minister for Information, Broadcasting and Tourism. However, in 1966 Oneko quit the government and joined the newly created Kenya People's Union, a socialist party led by his comrade Oginga Odinga.
Oneko returned to politics in 1992 when he was elected as an MP at the first multiparty elections in Kenya. He represented Ford-Kenya party, led by Oginga Odinga. However, he lost his Rarieda Constituency seat at the next elections held in 1997.
At the time of his death, Oneko was the only one of the "Kapenguria six" still alive. Mashujaa Day (previously known as Kenyatta Day until the promulgation of the new Kenya constitution on 27 August 2010) is a national holiday in Kenya that commemorates the detention of the Kapenguria Six on 20 October 1952.
