Iraqi President Barham Salih on Tuesday named politician Adnan Al-Zurfi to form a new government, according to the state television.
The broadcaster said Al-Zurfi was mandated to form the government within 30 days as per the constitution.
Al-Zurfi is a leading member of the Victory Alliance led by former Prime Minister Haidar al-Abadi, and he is also a former governor of the southern Najaf province.
Iraq has been roiled by mass protests since early October over poor living conditions and corruption, forcing Prime Minister Adel Abdul-Mahdi to resign.
More than 600 people have been killed and 17,000 injured in the protests so far, according to the Iraqi rights commission.
