List of Smallville episodes

Smallville is an American superhero television series developed by Miles Millar and Alfred Gough for The WB and The CW. The series follows the life of Clark Kent (Tom Welling), beginning when he is a teenager in the town of Smallville, Kansas, and continuing through high school, college, and his start at the Daily Planet before he adopts the "Superman" persona.

As the series progresses, Clark Kent copes with his emerging superpowers (x-ray vision, super hearing, etc.), exploration of his extraterrestrial origins and discovering his true destiny. The series also deals with the people in Clark Kent's life: his human parents, Jonathan Kent (John Schneider) and Martha Kent (Annette O'Toole); his friends Chloe Sullivan (Allison Mack) and Pete Ross (Sam Jones III); his love interest for seven seasons Lana Lang (Kristin Kreuk); Chloe's cousin and Clark's love interest since season eight, Lois Lane (Erica Durance); and his friendship with Lex Luthor (Michael Rosenbaum) and how this gradually decays into their mutual enmity of legend.

During the course of the series, 217 episodes of Smallville aired over ten seasons, between October 16, 2001, and May 13, 2011.

Notes

1. The writers consider "Absolute Justice" two separately produced episodes, but The CW broadcast them as a single episode, and later packaged it as a single episode in the season nine DVD. Therefore, "Absolute Justice" is both the 185th and 186th episode produced, but only the 185th episode aired.^[185][186]
2. The producers consider season nine's "Absolute Justice" two separately produced episodes, but The CW combined those two episodes into a single broadcast, and then packaged it in the season nine DVD as one episode as well. Therefore, "Absolute Justice" is both the 185th and 186th episode produced, but only the 185th episode aired. Thus, "Homecoming" is considered the 200th episode produced, but the 199th broadcast. The CW recognizes "Homecoming" to be the 200th episode.^[201][202]
