Lindsay Davenport is the daughter of Wink Davenport, who was a member of the U.S. volleyball team at the 1968 Summer Olympics in Mexico City, and Ann L. Davenport, the president of the Southern California Volleyball Association. Davenport was born to an athletic family. While her two older sisters, Leiann and Shannon, played volleyball, Lindsay began playing tennis at age six. She was coached by Robert Lansdorp, who had previously coached Tracy Austin. She attended Chadwick School in Palos Verdes Peninsula, California. At age 16, her family moved to Murrieta, California, where she attended and graduated from Murrieta Valley High School, and she began to work with, among others, Robert Van't Hof. At age 16, Davenport joined the United States Tennis Association junior national team. She had a rapid growth spurt — about six inches in two years — which affected her coordination, but did not hinder her performance. She excelled at junior level competitions and swept the singles and doubles titles at the National Girls' 18s and Clay Court Championships in 1991 and won the Junior U.S. Open in 1992.

She won the girls' 16s singles at the prestigious Ojai Tennis Tournament in 1990.

While Davenport's first play dated back to 1991, she officially became a professional two years after her first professional-level matches. Davenport's doubles success in 1993 was a 17–16 record while she reached the top 100 in doubles rankings. She reached the third round at the 1993 Australian Open doubles competition with Chanda Rubin. Davenport entered the top 20, despite coming into her first tournament that year ranked no. 162. She qualified for the 1993 Australian Open, reaching the third round before falling to Mary Pierce.

At the Indian Wells Masters, Davenport reached the quarterfinals ranked no. 99, but lost to 7th-ranked and future doubles partner Mary Joe Fernández. Later that year, Davenport won her first Tier III title at the WTA Swiss Open where she beat Nicole Bradtke in three sets in the finals. She reached the third round at the 1993 Wimbledon Championships, and at the 1993 US Open, the American reached the fourth round ranked no. 24. 1993 is also notable because it was the one time she faced Martina Navratilova, falling in three sets, 6–1, 3–6, 5–7, in the Oakland semifinals.

Davenport won the first professional tournament she entered in Brisbane, Australia. At the Australian Open, she reached her first Grand Slam quarterfinal, defeating no. 5 Mary Joe Fernández in the fourth round, before losing in the quarterfinals to top-ranked Steffi Graf. Davenport then reached the semifinals at Indian Wells, California and Miami and won the title in Lucerne. At Wimbledon, Davenport reached her second Grand Slam quarterfinal. Ranked ninth, Davenport defeated tenth ranked Gabriela Sabatini, before losing to third ranked Conchita Martínez, who went on to win the tournament. In November, she reached her first WTA Tour Championship final, losing to Sabatini.

In doubles, Davenport won Indian Wells with Lisa Raymond and reached the French Open doubles final with Raymond, where they lost to Gigi Fernández and Natasha Zvereva. Davenport teamed with Arantxa Sánchez Vicario to win the title in Oakland, defeating Gigi Fernández and Martina Navratilova in the final.
