Still, it's the 22nd time Clinton's been rated the most admired woman - more than any other man or woman ever on the list.
Last year, Obama topped the list with 22 percent, while Trump garnered 15 percent.
The more detailed data from Gallup showed Trump was tied for seventh with former Secretary of State Condoleezza Rice. They were followed by Pope Francis, who was the choice of three percent of respondents, and Rev. Billy Graham, who was picked by two percent.
Trump finished with just 14% support for the most admired man. Trump is the first incumbent president since George W. Bush in 2008 to not be named the most admired man in America.
Gallup has published the most admired man and woman list every year except for one since 1946.
Obama retaining his title this year is a bit unusual. The 2017 results fell along party lines, with 35 percent of Republicans naming Trump as their most admired, and only 1 percent naming Obama.
"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", Gallup writes.
Gallup said the poll of 1,049 adults was conducted between December 4-11 and has a margin of error of plus or minus four percentage points.
Concluding the national security strategy address that he delivered earlier this month, President Trump described his foreign policy aim "to celebrate American greatness as a shining example to the world". "She managed to win this year because she remains arguably more prominent than other contenders". "The percent who name Clinton is the lowest percentage she has received since 2002, when 7 percent named her in another close first-place finish".
