The freaky footage, which appears to show a shadowy figure flickering into view by the bar, was filmed at Ye Olde Man and Scythe in Bolton.
Manager Tony Dooley spotted the spectre when he checked the cameras on Friday morning and found they had mysteriously stopped recording at 6.18am.
"I came down and saw a glass smashed on the floor so I was instantly suspicious and went to check the CCTV and found it has stopped working," he said.
"We checked the footage and it revealed this figure.
"To be honest I was a bit concerned - I'm a bit of a sceptic when it comes to ghosts but you become more of a believer when you see things like that."
The pub, which dates from 1251, is the fourth-oldest pub in Britain and is reputedly haunted by the Seventh Earl of Derby, James Stanley.
