Kipruto Rono Arap Kirwa (born 1957) is a Kenyan politician who served as the 15th Minister of Agriculture between 2003 and 2008 in the Kibaki administration.
His father, Kiprono Cheptile Arap Sirng'ewo was a farmer and livestock keeper, who was among the Nandi people evicted from their fertile ancestral lands by the British colonialists in Nandi County to pave the way for white settlers to develop the area that became the white Highlands in the Rift Valley.
The late colonial senior chief Elijah Cheruiyot oversaw the issuing of the temporary British permit that allowed the families to enter the northern Tanganyika, settling in Mara, Musoma, Bunda and Mwanza in 1951.
When the NARC led by President Mwai Kibaki swept into power during the 2002 Kenyan general election, Kirwa was appointed to serve as the Minister for Agriculture.
Later he was nominated to serve as IGAD Special Envoy to Somalia Peace and National Reconciliation from 2008 to 2012.
