In the 1984 film Ghostbusters, what is the name of the green ghost known for causing chaos in the hotel?

Slimer is the answer. Slimer is the green ghost encountered by the Ghostbusters during the Sedgewick Hotel investigation in the 1984 film Ghostbusters.

The Green Ghost at the Sedgewick Hotel

The Sedgewick Hotel scene is one of Slimer’s key early appearances in Ghostbusters. During the investigation, the ghost races through the hotel, causes trouble for guests and staff, and becomes the team’s first major on-screen capture. Bill Murray’s Peter Venkman is famously covered in slime during the encounter, giving the scene one of the film’s most memorable supernatural comedy moments.

Slimer Was Not Named On Screen

Although the character is now widely known as Slimer, that name was not used for him in the original 1984 film. The green hotel ghost became more closely identified as Slimer later through The Real Ghostbusters animated series, toys, merchandise, and later Ghostbusters franchise material. That naming history is why some viewers remember the character from the movie without realizing the familiar name came afterward.

Why Slimer Became a Ghostbusters Icon

Slimer stood out because his design was simple, weird, and instantly recognizable. He was not the main threat in Ghostbusters, but the Sedgewick Hotel scene gave him a clear identity as the messy, unpredictable ghost tied to the team’s first successful capture. Over time, that made Slimer one of the best-known ghosts connected to the classic movie and the wider Ghostbusters franchise.
