Lucas Eugene Scott is a fictional character and formerly the main protagonist from The CW television series One Tree Hill, portrayed by Chad Michael Murray. Lucas is a talented basketball player and writer. He is rival to half-brother Nathan Scott, before the two eventually become close friends. While striving for his dreams, he must balance his tumultuous relationships with his father, Dan Scott, and the two females enveloping his love life, Peyton Sawyer and Brooke Davis.

The character has been described as popular among teenagers and young adults, not only for his skill at basketball but for his romantic aspirations. Specifically regarding the character's impact on female viewers, Entertainment Weekly stated, "Look into those soulful blue eyes and it's clear why One Tree Hill, in which Murray plays [the brooding basketball star], became a sleeper hit during its first season on The WB."

Chad Michael Murray was the first person to be cast for One Tree Hill. The producers were originally unsure as to who Murray would play. Series creator Mark Schwahn wanted him to play the character of Nathan Scott since Murray had played a bad guy several times before, and he felt it was only natural to give him this role. Murray, however, wanted to portray Lucas due to a connection he felt with the character. He felt that he could inhabit the character as the two share several similarities. Murray's mother left him when he was young, and Lucas was abandoned by his father. Murray's passion for the role led the producers to cast him as Lucas. Murray had turned down the lead role of Ryan Atwood in The O.C. to accept the role as Lucas Scott.
