Lee Krasner (October 27, 1908 – June 19, 1984) was an influential American abstract expressionist painter in the second half of the 20th century. On October 25, 1945, she married artist Jackson Pollock, who was also influential in the abstract expressionism movement.

Krasner was born as Lena Krassner (outside the family she was known as Lenore Krasner) in Brooklyn, New York to Russian Jewish immigrant parents from Bessarabia.

She studied at The Cooper Union and the National Academy of Design, and worked on the WPA Federal Art Project from 1935 to 1943. Starting in 1937, she took classes with Hans Hofmann, who taught the principles of cubism, and his influence helped to direct Krasner's work toward neo-cubist abstraction. When commenting on her work, Hofmann stated, "This is so good you would not know it was painted by a woman."

In 1940, she started showing her works with the American Abstract Artists, a group of American painters.

Krasner would often cut apart her own drawings and paintings to create collages and, at times, revised or discarded an entire series. As a result, her surviving body of work is relatively small. Her catalogue raisonné, published in 1995 by Abrams, lists only 599 known pieces. She was rigorously self-critical, and her critical eye is believed to have been important to Pollock's work.

Paul Jackson Pollock (January 28, 1912 – August 11, 1956), known as Jackson Pollock, was an influential American painter and a major figure in the abstract expressionist movement. He was well known for his uniquely defined style of drip painting.

During his lifetime, Pollock enjoyed considerable fame and notoriety. He was regarded as a mostly reclusive artist. He had a volatile personality, and struggled with alcoholism for most of his life. In 1945, he married the artist Lee Krasner, who became an important influence on his career and on his legacy.

Pollock died at the age of 44 in an alcohol-related car accident. In December 1956, the year of his death, he was given a memorial retrospective exhibition at the Museum of Modern Art (MoMA) in New York City, and a larger more comprehensive exhibition there in 1967. More recently, in 1998 and 1999, his work was honored with large-scale retrospective exhibitions at MoMA and at The Tate in London.

In 2000, Pollock was the subject of an Academy Award–winning film Pollock directed by and starring Ed Harris.
