But security experts say it is unclear whether such strikes can do much to hinder Islamist militants who have long menaced communities in the area.
Trump announced on Truth Social that US forces had launched a "powerful and deadly" strike against Islamic State militants in northwest Nigeria at the request of Nigeria's government.
He said the group had been targeting Christians in the region.
Local media reported loud explosions in the village of Jabo on the evening of Christmas Day. Reuters has not been able to confirm whether there were casualties.
Trump said a US military strike targeting Islamic state militants in Nigeria was originally supposed to take place on Wednesday, but he ordered it delayed by a day.
"They were going to do it earlier," Trump told Politico in an interview. "And I said, 'nope, let's give a Christmas present.' … They didn't think that was coming, but we hit them hard. Every camp got decimated."
A US defence official, speaking on the condition of anonymity, told Reuters that the strike was carried out by about a dozen Tomahawk missiles launched from a US Navy warship in the Gulf of Guinea.
Abuja confirmed it had approved the operation. Foreign Minister Yusuf Tuggar said on Friday that Nigeria had acted jointly with the US, but that no specific religion had been targeted.
"Nigeria is a multi-religious country, and we're working with partners like the US to fight terrorism and protect lives and property," Tuggar told Nigeria's Channels Television.
After the strike, US Defence Secretary Pete Hegseth said on X there was "more to come."
The US official said another strike did not appear imminent, but did not rule out future operations.
This specific strike was carried out by the United States, the official said, in part because the location was too remote for Nigerian forces to reach.
"It's partially symbolic," the official said, adding that the aim was also deterrence and to send a message that the Trump administration was prepared to use the military.
The northwestern area where Thursday's air strike took place has been plagued since 2024 by increasing violence from members of the Lakurawa sect, a strict Sunni Islamist movement that claims affiliation with the Islamic State group.
Formed as a vigilante outfit, the group evolved into a jihadist movement enforcing strict Islamist rule across hundreds of villages in the area. Nigeria declared the group a terrorist organisation early this year.
"It's very likely this is the group Trump referred to when mentioning US military strikes in Nigeria," said Confidence MacHarry, senior analyst at Lagos-based SBM Intelligence.
"They've also been linked to widespread cattle theft, with most of the stolen animals ending up in markets along the Nigeria-Niger border."
Cameron Hudson, a former US official who worked on Africa-related issues, said the strike was unlikely to have a big impact in the near term.
"It's not realistic to think that a few cruise missiles are going to change much in the short term," Hudson said. "The Trump administration will have to demonstrate its own long-term commitment to ending this militancy if it hopes to have any effect."
Nigeria's population of over 230 million people is roughly evenly divided among Christians, who predominate in the south, and Muslims, who predominate in the north.
