This was the sixth consecutive win for Obama, who took 16 percent of the vote, and the 12th straight year for Clinton, who took 15 percent, Gallup reported.
Gallup said 7 percent of respondents named Nelson Mandela as the most admired man; however, because pollsters specifically ask about a living man or woman, deceased figures do not make the official list.
This was Clinton's 18th time at the top of the list, but the first time she hasn't held an official government role during the poll.
Gallup questioned 1,031 adults nationwide Dec. 5-8. The poll has a margin of error of 4 percentage points.
