It’s a knockout!

A landmarked, $49.5 million Gilded Age mansion in the heart of Manhattan has caught the eye of famed boxing champ Floyd Mayweather Jr.

After recently touring the city’s most expensive rental, as Gimme Shelter exclusively reported — a $150,000-a-month Soho penthouse owned by former Uber CEO Travis Kalanick — Mayweather has moved his house hunt to Midtown, we can reveal.

The retired boxing champ, who boasts 30 million followers on social media, is also a real estate investor whose massive portfolio includes 1,000 units of affordable housing, as well as luxury assets in the city.

He was recently spotted looking at 9 W. 54th St., a 50-foot-wide brick and limestone mansion off of Fifth Avenue, across the street from the Museum of Modern Art. The mansion is a combination of two separate townhouses.

The current seller bought the building for $55 million in 2019.

The property was built in 1898 for JP Morgan’s cousin and business partner, James Goodwin. It was designed by the famed architectural firm McKim, Mead & White, whose other landmarks include the University Club of New York, the original Penn Station, the Brooklyn Museum, the New York Public Library and the main campus of Columbia University.

The five-story neo-Georgian pad comes with 11 bedrooms.

Original details include 12 fireplaces, hand-crafted woodwork and millwork, multiple columns, wood floors and stained glass. There’s also a walk-in safe for the original owners’ silver in the octagonal dining room and a 17-foot-deep bank vault with bullet-proof windows, as the building also once served as headquarters for the US Trust Company.

It is currently zoned for mixed use, so it can serve as an office, a gallery, a private club or an embassy — otherwise, it can be transformed back into its original single-family mansion status, the listing notes.

It all opens with a wood-paneled entry gallery, a library, a reception room and other great spaces. Two staircases, with original skylights above, lead to a parlor floor with ceilings just under 14 feet high. Two large rooms here have floor-to-ceiling windows, along with five Juliet balconies with “tree-lined street views” of MoMA’s sculpture garden. There’s also a library, a butler’s pantry in the dining room and a glass conservatory overlooking a garden.

The following floors, three to five, can be configured to suit the buyer. A windowed basement with French doors leads to a landscaped garden with two front entrances.

The listing brokers are Patricia Vance and Sandra Ripert of Douglas Elliman, who declined to comment.
