State Assemblywoman Jenifer Rajkumar is eyeing a run for New York City comptroller after using her “close friend” Mayor Eric Adams to raise her profile in the Big Apple, The Post has learned.

The Queens Dem, well-known for donning scarlet red dresses as she tags along with the mayor at seemingly every press conference or rally across the five boroughs, has been lining up support over the past few weeks for her plan to run for citywide office, according to knowledgeable sources.

Rajkumar has been setting up meetings with union heads and faith leaders as well as prominent local Democrats and strategists as part of her plan, sources said.

Her expected run comes after months of speculation about which citywide elected spot she was gunning for in the 2025 primary.

She is slated to challenge incumbent Brad Lander, a constant foil to the Adams administration, often criticizing how it runs the city.

That’s if Lander chooses to run for reelection.

Political sources have told The Post that Lander is interested in challenging Adams for mayor but that no formal decision has been made.

It is unclear when Rajkumar might formally announce her bid for the seat. Calls to her office from The Post were not immediately returned Tuesday.

Rajkumar got her start in Lower Manhattan in 2011 when she won district leader not long after moving to the area. But her two subsequent runs for office, once in 2013 for City Council and again in 2016 for Assembly Speaker Sheldon Silver’s vacated seat, were both lost.

She ran again in 2020 after moving to southern Queens and beat out an 11-year incumbent in the state assembly’s District 38.

Supporters of the lawmaker who spoke with The Post praised Rajkumar for her work ethic and how she relates with the community.

“Half the battle is showing up, and she is and doing it early,” said City Council member Kalman Yeger (D-Brooklyn).

Over the past few years, Rajkumar has proven to be a staunch supporter of Adams, pushing the mayor’s legislative agenda in Albany and even coming to his defense after he was accused of sexual misconduct decades earlier in a lawsuit.

In exchange, Rajkumar has become a staple and welcomed at the mayor’s events — the vast majority of which have been outside her districts — allegedly in an attempt to increase her name recognition.

The two have repeatedly referred to each other as “close friends” at events.

“It was genius to hitch onto the mayor of the city of New York to get known so she could get catapulted into the spotlight to get ready for a citywide run,” one political strategist quipped.

But the source said her campaign could get tricky if former Gov. Andrew Cuomo makes his long-rumored entrance into the fold for mayor, given her strong ties to both pols.

“She’d have to run an independent campaign,” the source said.

But another Dem operative raised concerns over her being tied to Adams, whose campaign will have to rebound from lagging poll numbers during the cloud of a federal probe.

“She is better off staying in the Assembly than tying herself to Eric Adams in a citywide race for comptroller next year,” the source said, adding that Adams’ “poll numbers are historically low, and he’s facing legal issues that could well get worse.”
