President Obama spoke with French President Francois Hollande on Friday evening, the White House said.
Earlier in the day, Obama said he had chosen not to call the French leader because "my expectation is that he is very busy at the moment."
According to a readout of the call, Obama offered Hollande condolences on behalf of the American people and "reiterated the United States' steadfast, unwavering support" for France.
Obama repeated his offer of "any necessary support" in the investigation, and both leaders "pledged to work together, and with nations around the world, to defeat the scourge of terrorism," the White House said.
The two leaders had spoken earlier in the day, before the attacks, in preparation for the G-20 summit starting Sunday in Turkey. Shortly after the attacks, Hollande announced he was canceling his trip to Turkey.
