Andrew Yang’s decision to drop his bid for the White House Tuesday night has fueled immediate speculation that the entrepreneur will set his sights on City Hall.

Shortly after Yang dropped his long-shot presidential bid, Democratic consultants and other operatives throughout the Big Apple were buzzing about him potentially running for New York City mayor in 2021.

“@AndrewYang would make a very interesting candidate for NYC Mayor in 21,” tweeted Howard Wolfson, a top adviser to presidential candidate and former Mayor Michael Bloomberg.

“It’s a natural next step,” a city-based Democratic consultant told The Post when asked about a potential Yang mayoral candidacy. “With the notoriety and following he’s gathered, he has to be taken seriously.”

Yang’s camp did not immediately return messages.

The field of candidates to replace term-limited Bill de Blasio currently includes Council Speaker Corey Johnson, Brooklyn Borough President Eric Adams and Comptroller Scott Stringer.
