Lee Eastman (born Leopold Vail Epstein; January 12, 1910 – July 30, 1991) was an American show business lawyer and art collector from New York City.

Eastman was also the friend and longtime lawyer for and collector of the works of the abstract expressionist painter Willem de Kooning.

His sister Rose Frisch became a noted scientist who worked on issues of women's fertility and population studies.

[4][5] McCartney wanted Eastman, but was out-voted 3–1, as George Harrison and Ringo Starr sided with Lennon and Klein.

Subsequent disagreements over decisions made by Klein and the other Beatles prompted McCartney — represented by Eastman — to sue them to dissolve the partnership, and he eventually succeeded.

In 1984, McCartney cited one example of advice he received from Eastman: The music publishing I own is fabulous.

[9] Eastman had four children with his first wife Louise Lindner, herself the daughter of a prominent Cleveland department store executive.
