The study conducted just days after President Vladimir Putin secured permission from parliament to launch air strikes in Syria found that most Russians approve of his latest decision to use force abroad.
The launch of strikes in Syria is Russia's first major military involvement outside former Soviet Union territory since the invasion of Afghanistan in 1979.
Seventy two percent of respondents said they approved of the bombing campaign and 46 percent said they agreed with the decision of the rubber stamp parliament's upper house to allow Putin to use force abroad, said the independent Levada Centre.
"Support for actions of the Russian military in Syria is an approval rating of a television programme rather than an indicator of the mobilisation of Russian society," said Levada Centre researcher Denis Volkov.

"Declaring one's readiness for war reflects perceptions about the might of the Russian military machine and the army's symbolic authority rather than one's readiness to take up arms."
Last month 69 percent of respondents to a similar Levada poll said they opposed Moscow's deployment of troops in Syria, with just 14 percent in favour.
