Who was the first American to orbit the Earth?

Astronaut John Glenn became the first American launched into orbit. Traveling aboard the "Friendship 7" spacecraft, Glenn reached an altitude of 162 miles (260 kilometers) and completed three orbits in a flight lasting just under five hours. Glenn was the third American in space, preceded by Alan Shepard and Virgil "Gus" Grissom who had each completed short sub-orbital flights. All of them had been preceded by Russian cosmonaut Yuri Gagarin who was the first human in space, completing one orbit on April 12, 1961 - a feat that intensified the already ongoing Space Race between the Russians and Americans. Glenn's successful flight showed the Americans had caught up and was followed in September 1962 by President John F. Kennedy's open call to land an American on the moon before the decade's end.
