The seventh season of the American fictional drama television series ER first aired on October 12, 2000, and concluded on May 17, 2001.

In the midst of being remodeled, for a more open, safe floorplan, the show's seventh season starts with John Carter completing his drug rehabilitation and trying to be who he was before he got stabbed, with the support of Abby Lockhart.

Abby's own life is in disarray after she is forced to drop out of medical school, her bipolar mother Maggie Wyczenski comes to stay, her new romance with Luka Kovač hits many pitfalls, and she reaches a crossroads in her Nurse position at County.

Long-time crew member Joe Sachs joined the production team as a co-producer for the seventh season and was promoted to producer mid-season.

Tom Garrigus joined the writing staff as an executive story editor and contributed to two episodes but left the crew with the close of the season.

Returning directors were executive producer John Wells, cast members Anthony Edwards and Laura Innes, series veterans Lesli Linka Glatter, Félix Enríquez Alcalá, David Nutter, Marita Grabiak, and Tom Moore.
