The poll, conducted by the American Jewish Committee Sept. 6-17 among 1,040 Jewish voters nationwide, found 10 percent were undecided, the Jewish Telegraphic Agency reported Friday.
Obama is favored by Jews of all religious backgrounds with the exception of Orthodox Jews, who favored the Republican nominee, the poll found.
Overall, most respondents said they approve of the work Obama is doing in office. Sixty-three percent said they approved of his performance on the economy, while 37 percent did not, and 68 percent approved of Obama's work on healthcare, while 32 percent did not.
Romney's campaign has criticized Obama on U.S. support for Israel, and the issue is likely to come up at the first presidential debate between the two Oct. 3.
During his address Thursday at the United Nations in New York, Israeli Prime Minister Binyamin Netanyahu said the Obama administration has been supportive of Israel's efforts to prevent Iran from acquiring nuclear weapons.
"I very much appreciate the president's position as does everyone in my country," he said. "We share the goal of stopping Iran's nuclear weapons program."
Netanyahu said he is confident Israel and the United States "can chart a path forward together."
The poll has a margin of error of 5 percentage points.
