"Kobol's Last Gleaming" is the two-part first-season finale of the reimagined Battlestar Galactica television series.

In the first part, the human fleet discovers the abandoned planet Kobol, the mythical birthplace of humanity, who left here and founded the Twelve Colonies of Kobol elsewhere in the galaxy. A survey team is stranded there by Cylons while President Laura Roslin convinces Starbuck to disobey orders and retrieve an artifact called the Arrow of Apollo. In the second part, Commander William Adama stages a military coup and places Roslin in Galactica's brig. Starbuck retrieves the Arrow and discovers that Boomer, still on Galactica, is a Cylon. This Boomer destroys the Cylon Basestar orbiting Kobol, returns to Galactica, and shoots Commander Adama; the season ends on a cliffhanger.

"Kobol's Last Gleaming" underwent numerous substantial rewrites. It was one of the most expensive episodes of the first season to produce. The episode received favorable critical review. Michael Hickerson of Slice of SciFi ranked it as the fourth best episode of the re-imagined Battlestar Galactica. Simon Brew of Den of Geek called it "just outstanding television."
