West Germany's Steffi Graf defeated Argentina's Gabriela Sabatini in the final, 6–3, 6–3 to win the gold medal in Women's Singles tennis at the 1988 Summer Olympics.

The final was a rematch of the U.S. Open final earlier that year, where Graf also prevailed to complete the Grand Slam. The United States' Zina Garrison and Bulgaria's Manuela Maleeva-Fragnière won the bronze medals. It was the first medal in the event for West Germany, Argentina, and Bulgaria, while the United States had previously earned medals in both of its prior appearances in 1900 and 1924.
