Jones has been leader of the Labour Party in Wales and first minister since December 2009.
Addressing the Welsh Labour conference in Llandudno on 21 April, Jones said he would stand down in the autumn in time for a new Welsh leader to replace him by the end of the year.
“At that point it will make sense to have a fresh start. For my family, for my party and for my country,” he told delegates.
“I am incredibly proud of what we have achieved together so far. The election victories. The landmark legislation. A better deal for nurses, for students and our businesses. Putting Wales on the map.”
Jones has been under pressure over his response to the death of Carl Sargeant, who had served in a variety of ministerial roles in Jones’ administration.
Sargeant took his own life last November after he was sacked following allegations of sexual harassment.
An inquiry into how the sacking was handled has been ordered but has not yet begun.
