It has Mary Lou McDonald's party on 24%, tied with Fianna Fáil and three ahead of Fine Gael.
The Red C poll for the Business Post has Sinn Féin up 5% to 24% support. Overall Mary Lou McDonald's party has seen its support jump 13% in Red C polls since November.
It is level with Fianna Fáil, which is down two points to 24%.
Fine Gael now lies in third place with 21% support, down two points on the last poll.
This survey of 1,000 voters was taken in the six days up to last Thursday.
It has the Greens on 7% Labour on 5%, the Social Democrats with 3%, Aontu with 2% and Solidarity People Before Profit with 1% support.
