Zohran Mamdani is planning himself a party.
The socialist mayor-elect will throw a blowout bash — closing off streets and packing the area around City Hall with tens of thousands of people — to celebrate his incoming administration on January 1, The Post has learned.
The mayoral transition has been planning the massive gathering in downtown Manhattan, which will shut down Broadway south of Canal Street — a stretch known as the Canyon of Heroes that is typically used for ticker-tape parades, sources said.
The inauguration plans were described by insiders as a massive festival or street fair, with the transition expecting between 40,000 and 50,000 attendees.
“He wants some sort of ‘man of the people’ display around City Hall,” one source said.
The transition is expected to foot the bill for the event, but insiders pointed out that the bash will surely put a strain on the NYPD and other city workers after the New Year’s Eve celebration in Times Square the night before.
At least 120 cops are expected to have to work overtime hours for the event, sources said.
“So, all the expensive big money donors will be paying?” one Democratic source asked. “I thought this was the populist change from the corrupt Adams administration — but I’m glad they see [that] if they want to do something, it costs money.”
Heading up the planning for the transition is former Mayor Bill de Blasio’s staffer, Ellyn Canfield, who worked under him as the head of mayoral events and street permitting.
Insiders also questioned hosting an outdoor fair in what could be a bitterly cold January — just hours after the city rings in the new year.
“A street fair in January?” the first source joked.
The winter block party would mark a sharp departure from the last three mayors.
Mayor Eric Adams famously used the Times Square New Year’s Eve bash as a lively backdrop when he was sworn in in 2022.
His predecessors Bill de Blasio and Michael Bloomberg each held their swearing-in ceremonies on the steps of City Hall, with hundreds on onlookers filling the plaza in front.
