|Date of death||14 March T.A. 3019|
Gorbag was the captain of the Uruks of Minas Morgul. He served the Nazgûl who dwelt in the Dead City. However, due to the Silent Watchers exhibiting unease after Frodo Baggins had passed by them, Gorbag and a patrol was sent to Cirith Ungol where Shagrat was in command.
On 13 March T.A. 3019 Gorbag and Shagrat came across Frodo, who had been paralysed by Shelob. They ordered Frodo carried back into the Tower of Cirith Ungol as their prisoner. During their return to the tower Sam, who was wearing the One Ring, overheard them talking.
In their conversation Gorbag was clearly smarter than his companion: After Shagrat says that the Nazgûl were uneasy and that something nearly slipped Gorbag says that something had slipped. Shagrat says that Shelob got him, meaning Frodo, but Gorbag points out that there must have been more than one because someone else cut the cords from Frodo. Shagrat dismissed Gorbag's reasoning by claiming that he always took a gloomy view. Shagrat, who had been in the tower longer, was able to tell Gorbag that Frodo was not dead.
On 14 March the two Orc leaders stripped Frodo of his possessions. Upon discovering Frodo's Mithril coat Gorbag tried to keep it, which provoked a fight between Gorbag's and Shagrat's followers. Gorbag knifed Shagrat but Shagrat throttled him.
- Portrayed by Peter Tait, Gorbag is portrayed as a smaller Orc while Shagrat is a Uruk. It also shows Samwise Gamgee killing Gorbag rather than Shagrat.
- Gorbag appears as a boss at the end of the "Cirith Ungol" level. In the game, Gorbag knocks down Shagrat and then Sam must defeat him by stunning him with pikes.
