In the statement, Obama praised Williams' entire career, from the voice of the genie character in "Aladdin" to a comedian who cheered up U.S. troops abroad.
"Robin Williams was an airman, a doctor, a genie, a nanny, a president, a professor, a bangarang Peter Pan, and everything in between. But he was one of a kind. He arrived in our lives as an alien - but he ended up touching every element of the human spirit. He made us laugh. He made us cry. He gave his immeasurable talent freely and generously to those who needed it most - from our troops stationed abroad to the marginalized on our own streets," Obama said in the statement.
The president also said his entire family extended their condolences to the late actor's friends, family, and fans.
"The Obama family offers our condolences to Robin's family, his friends, and everyone who found their voice and their verse thanks to Robin Williams," he concluded.
The investigation into the cause of Williams' death is ongoing.
