More than half of people would back controls to cap high rents in cities like Aberdeen.
Almost 54% of people would support measures to reduce the cost of letting a property, while only 12% would oppose such a move, according to the Survation study.
The Scottish Government is currently pushing legislation through parliament that could see rent controls introduced in “pressured areas”.
Landlords have warned that “heavy handed” intervention in the market “will only endanger investment in the private rented sector”.
Aberdeen has some the highest property values and rents in Scotland.
Green Party co-convener Patrick Harvie will join north-east candidate Maggie Chapman in the Granite City later today to discuss the issue with house hunters.
Ms Chapman said: “Better housing is a fundamental part of a better society. We must secure affordable, well maintained homes for all if we are to improve people’s health and well-being, and have a fairer, more equal economy.
“Across Scotland, we see rent increases outstripping household income. These increases make housing unaffordable in many of our cities and also in rural hot spots. We must put in place rent controls that will return rents to affordable levels.
“We also must crack down on bad landlords.
“We need, urgently, to properly regulate letting agents. Private tenants should never face the prospect of eviction simply for raising concerns about poor quality housing.”
The Survation poll, which was commissioned by the Green Party, asked 1,033 Scots whether they would support or oppose proposals for the government to introduce a points-based “rent control” system.
A fifth of people said they would “strongly support” such a move, while a third said they would “somewhat support” the proposal.
Over a fifth said they were indifferent either way.
