Clinton is being treated for the flu, Angel Urena, Clinton’s deputy chief of staff, said in a statement about his release.
“He and his family are deeply grateful for the exceptional care provided by the team at MedStar Georgetown University Hospital and are touched by the kind messages and well wishes he received,” Urena said.
“He sends his warmest wishes for a happy and healthy holiday season to all,” Urena said.
The 78-year-old Democrat was hospitalised on Monday afternoon for testing and observation.
Clinton served two terms as president from January 1993 until January 2001.
He addressed the Democratic National Convention in Chicago this summer, and campaigned in the fall for Democratic Vice President Kamala Harris, who lost the election to Republican Donald Trump in November.
Clinton recently published his newest book, Citizen, a memoir about his life after the White House and the role of philanthropy in it.
