Jeff The Killer is a creepypasta character and a minor antagonist in SuperMarioLogan. He is protrayed by Logan and Lance's cousin; Matthew.
In Happy Halloween!, it is known that he is afraid of chickens and he doesn't like people walking into his house. If someone does either of these, he'll try to shoo them away with whatever his holding. He also mocks Jeffy.

- It is unclear whether the character in SML is supposed to actually be Jeff the Killer or just someone in a Jeff the Killer costume.
- It is revealed in an SML livestream that Logan's cousin Matthew plays Jeff the Killer.
