However, Obama comes in second place with 10 wins and won the title of the most admired man all eight years of his presidency.
Gallup said about one-quarter of respondents could not name a man or woman they admire most, roughly similar to last year's share who offered no opinion in response to the question.
The survey, which polled more than 1,000 American adults from December 4 to 11, found that 17 percent of respondents most admire Obama, compared to 14 percent who most admire Trump. But Trump's unpopularity kept him from the top spot, by a margin of 3 percent.

The former secretary of state has held the title of "most admired" woman for a total of 22 times. "The incumbent president is the usual victor, since he is arguably the most prominent figure in the country - but when the president is unpopular, other well-known and well-liked men have been able to finish first". Other men on the list include Pope Francis, John McCain, Elon Musk, Bernie Sanders, Bill Gates, Mike Pence, and The Dalai Lama.
Donald Trump trailed Obama in second place for the men while Michelle Obama was close behind Clinton in second place for the women. Another 9 percent name a friend or relative as their most admired man, with 13 percent doing the same for most admired woman.
In the 71 years Gallup has gathered information, the present president has won the best title 58 times.
Eleanor Roosevelt is a distant second, getting 13 most honorable mentions in the poll.
