Mwai Kibaki, Kenya's third president from 2003-2013, has died aged 90.
Kibaki's death was announced by current Kenyan President Uhuru Kenyatta.
While announcing Kibaki's death, Kenyatta recalled his long public service, including being a member of parliament for five decades.
"Kibaki was a quintessential patriot whose legacy of civic responsibility will continue to inspire generations of Kenyans long into our future," Kenyatta said in a televised address.
Kenyatta did not state the cause of death but Kibaki has been ailing for some time, domestic media reported.
Kibaki is credited with reviving Kenya's then ailing economy, but his tenure was marred by deadly violence that killed more than 1,200 Kenyans following his disputed re-election in December 2007.
