Niger's ruling junta in April ordered the US to withdraw its nearly 1,000 military personnel from the country following a coup last year in the West African nation.
"Thanks to effective cooperation and communication between the Nigerian and American armed forces, this operation was completed ahead of schedule and without any complications," Niger's defence ministry and the US Department of Defense said in a joint statement.
The focus will next shift to withdrawal from the $100 million drone base near Agadez in central Niger, which had provided crucial intelligence about jihadist-linked groups, US Air Force Major General Kenneth Ekman said on Friday.
The pullout from that base, known as Air Base 201, will likely take place in August, he said.
Niger's ruling junta has given the US until Sept. 15 to remove troops from its territory.
In April, Russia sent military trainers to Niger.
Niger and its military-led neighbours Mali and Burkina Faso signed a confederation treaty on Saturday, signalling an ever-closer alignment between the countries in the insurgency-torn central Sahel.
They have torn up defence agreements with US, European and United Nations forces.
