Andrew Cuomo for president?! Four more years as governor?!

Gov. Cuomo held a swanky, hush-hush fundraiser at the posh St. Regis hotel in midtown Thursday night — while in the midst of negotiations with state lawmakers to adopt a $173 billion budget by April 1.

And wouldn’t you know? Donors with business before Albany were among those who attended the big bucks event.

Cuomo, who was just overwhelmingly re-elected to a third, four-year term in November, was seen walking into the St. Regis about 6:30 p.m.

Among those seen at the bash was Kennth Raske, head of the New York Greater Hospital Association, whose organization is fighting to block any reduction in Medicaid funding to medical facilities.

Raske got up and praised the governor for his work on health care, an insider said.

There were also reps from the cannabis industry there as Cuomo and lawmakers discuss whether to legalize the recreational use of marijuana.

Other attendees included reps from the Cable TV industry, the limousine association and financial services — all licensed and regulated by the state.

And there were labor leaders present, including Danny Donohue, president of the Civil Service Employees Association, the largest union representing state government workers.

The campaign soiree, where filet mignon and braised beef was served, raised eyebrows among government watchdog groups pushing for new laws to curb massive campaign contributions from special interests and pay-to-play politics.

“Ideally there shouldn’t be fundraisers during budget negotiations or during the time the Legislature is in session,” said Susan Lerner, director of NY Common Cause.

During his speech, Cuomo railed against the opposition that caused Amazon to cancel its plan to open new headquarters on the Queens waterfront. He called the resistance “the stupidest thing I’ve ever seen.”

He also discussed the importance of coming up with financing to fund the MTA.

He bashed President Trump’s spending plan and the new federal law that caps at $10,000 the amount of state and local tax taxes that New Yorkers can deduct on their federal tax returns.

But Team Cuomo treated the event as a dirty secret. It wasn’t mentioned on his schedule nor was it posted on his campaign website.

A Post reporter ran into a Cuomo advance aide outside the catering room at the St. Regis. He declined comment.

Cuomo’s press office declined comment.

A source said donors were asked to kick in up to $25,000.
