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.

With the win, Graf completed the Golden Slam, having also won all four majors earlier in 1988.

The United States' Zina Garrison and Bulgaria's Manuela Maleeva-Fragnière won the bronze medals.

The tournament was held from 23 September to 1 October at the Seoul Olympic Park Tennis Center.
