Only 29 percent of respondents favor a "firm stand" against Russian actions, with 56 percent saying the United States "should not get too involved" in the issue, the Pew Research Center poll indicated.
A poll last year regarding possible U.S. intervention in Syria yielded similar results, the Washington Post noted Tuesday.
Opposition to involvement in Ukraine in Tuesday's poll crossed party lines, with more than 50 percent of Democratic, Republican and independent respondents expressing opposition to an active role in the Ukraine conflict.
The poll was conducted March 6-9 of 1,003 adults across the country, and has a margin of error of 3.6 percentage points.
