Van Sant was born in Louisville, Kentucky, the son of Betty (nee Seay) and Gus Green Van Sant, Sr; Gus's father was a clothing manufacturer and traveling salesman who rapidly worked his way into middle class prosperity, holding executive marketing positions that included being president of the White Stag Manufacturing Company's Apparel Operation. As a result of his father's job, the family moved continually during Van Sant's childhood. His paternal family is of partial Dutch origin; the name "Van Sant" is derived from the Dutch name "Van Zandt".

Drugstore Cowboy's exploration of the lives of those living on society's outer fringes, as well as its Portland setting, were mirrored in Van Sant's next effort, the similarly acclaimed My Own Private Idaho (1991). Only with the success of Cowboy was Van Sant now given license to make Idaho (a film he had originally pitched but was knocked back several times as the script was deemed 'too risky' by studios). Now New Line Cinema had given Van Sant the green light, he was on a mission to get the Idaho script to his first choices for his two young leads. After months of struggle with agents and managers over the content of the script, Van Sant finally secured River Phoenix and Keanu Reeves in the roles of Mike Waters and Scott Favor. Centering around the dealings of two male hustlers (played by Phoenix and Reeves), the film was a compelling examination of unrequited love, alienation, and the concept of family (a concept Van Sant repeatedly explores in his films). The film won him an Independent Spirit Award for his screenplay (he had won the same award for his Drugstore Cowboy screenplay), as well as greater prestige. The film also gained River Phoenix best actor honors at the Venice Film Festival among others. In addition, it helped Reeves--previously best known for his work in the Bill and Ted movies--to get the critical respect that had previously eluded him.  Van Sant's next film, a 1993 adaptation of Tom Robbins' Even Cowgirls Get the Blues, was an excessive flop, both commercially and critically. Featuring an unusually large budget (for Van Sant, at least) of $8.5 million and a large, eclectic cast including Uma Thurman, John Hurt, Keanu Reeves and a newcomer in the form of River Phoenix's younger sister Rain (at Phoenix's suggestion), the film was worked and then reworked, but the finished product nonetheless resulted in something approaching a significant disaster.  Van Sant's 1995 film To Die For helped to restore his luster. An adaptation of Joyce Maynard's novel, the black comedy starred Nicole Kidman as a murderously ambitious weather girl; it also stars Matt Dillon as her hapless husband and, the third Phoenix sibling in as many projects, Joaquin Phoenix, as her equally hapless lover (River had died from a drug overdose a year and half earlier). It was Van Sant's first effort for a major studio (Columbia), and its success paved the way for further projects of the director's choosing. The same year, he served as executive producer for Larry Clark's Kids; it was a fitting assignment, due to both the film's subject matter and the fact that Clark's photographs of junkies had served as reference points for Van Sant's Drugstore Cowboy.
