The big man on campus is back.

Barron Trump was spotted Tuesday strolling through New York University’s campus for the first time since his father, President Trump, was inaugurated on Jan. 20.

The fresh-faced first son sported a cream-colored sweater over a white polo shirt that he paired with black jeans and a pair of sneakers.

The 18-year-old seemingly skipped the first few weeks of classes, which started three days before his father was sworn into office to start his second term as commander-in-chief.

Barron arrived on campus from Trump Tower with a five-SUV motorcade while the Secret Service and NYPD monitored the area, according to Page Six.

The teen enrolled in the Stern School of Business after graduating from Florida’s elite Oxbridge Academy last year.

“He loves his classes and his professors,” his mother, first lady Melania Trump, told Fox News’ “The Five” in October.

The 6-foot-7 youngest Trump son aims to follow in his mogul father’s footsteps by launching a luxury real estate venture with two business partners.

One co-founder, Cameron Roxburgh, told Newsweek the company — Trump, Fulcher & Roxburgh Capital Inc. — will center on high-end real estate projects, including golf courses and properties in Arizona, Idaho and Utah.

It has listed Mar-a-Lago in Palm Beach, Florida, as its principal address, according to records obtained by The Post.

Though Barron hasn’t been able to have a “normal” college experience due to his father, he is “really popular with the ladies,” a source told People in December.

“He’s tall and handsome. A lot of people seem to think he’s pretty attractive — yes, even liberal people like him,” the insider added.
