All you need is love — and $3.79 million to spend.

This four-bedroom, four-bathroom duplex co-op at 140 East 83rd St. includes a sweet piece of New York City Beatles history.

The sprawling unit — now a combination of three apartments — includes Linda McCartney’s former studio, #10D. This is where she lived with her daughter Heather when she was merely an heiress, then named Linda Eastman, while running her photography business before she married Paul McCartney, according to reports.

The apartment was also not far from her parents, who lived on Park Avenue, natch. Linda’s father represented Paul from this apartment in his business dealings with the rest of the Beatles.

While Linda and Heather moved to England in 1968, she kept the apartment for quite some time before her untimely death of cancer in 1998.

The now-expanded home boasts parquet floors, city views from every room and a chef’s kitchen.
