- Gwen Stacy — Peter's first real girlfriend, whom the Green Goblin kills by throwing her off a bridge. The 2004 storyline "Sins Past" has Gwen, pregnant by Norman Osborn, secretly giving birth to twins, who, told by Norman that Spider-Man had killed their mother, attempt to kill Spider-Man in revenge as adults. In House of M, Gwen is still alive and married to Peter.
- Debra Whitman — a fellow Empire State University student and secretary whom Peter dates for a period of time, though his frequent disappearances complicate their relationship. Debra lacks self-confidence and their relationship is rather one-sided; Peter has little interest in her.

Soon afterward, she leaves New York after another man, Biff Rifkin, confesses his feelings for her.

- Desiree Winthrop — a wealthy young woman with limited psychic powers, of which she was unaware.
