"At this time, there is no evidence of gunshots. There is no evidence of a shooter. And there's no evidence of any victims today," District Mayor Muriel Bowser said at a news conference.
The U.S. Navy also confirmed there was no sign of a shooting.
"All personnel OK," the Navy said in a tweet. "Follow-on NCIS investigation ongoing."
The report that came in at 7:29 a.m. ET resulted in a lockdown/shelter-in-place at the Navy Yard.
"We've spoken with the person who called and have no concerns of a hoax, whatsoever," D.C. Police Chief Cathy Lanier said.
Police, the FBI, federal marshals and ambulances swarmed to the scene, and police blocked nearby streets, as speculation built over what — if anything — was going on inside.
In 2013, a mass shooting at the Navy Yard killed 12 people, along with the gunman.
Vice Adm. Dixon R. Smith, commander, Navy Installations Command, told reporters that experience helped the Navy provide "have counselors and chaplains" to those who were evacuated from the Navy Yard.
