Robert Seymour (c. 1955 – 15 June 1988) was a Northern Irish loyalist from Belfast who was a member of the Ulster Volunteer Force (UVF).

He served as the paramilitary organisation's East Belfast commander before being shot dead by the Provisional IRA behind his video shop in that part of the city in June 1988.

Seymour's conviction was overturned in the Appeal Court after the judge found the testimony of supergrass Joe Bennett "unbelievable".

This feat, along with the shooting of such a high-ranking IRA member in the Irish republican stronghold of west Belfast, made him a local legend and loyalist folk hero.

[3] In 1983, Seymour and UVF battalion commander John Wilson were convicted of the murder and sentenced to life imprisonment on the evidence of supergrass Joe Bennett.

He made an attempt to escape by running out of the back door; however, he was cornered by the gunmen in an entry behind his shop and shot dead.

[11]The UVF retaliated the following month by fatally shooting IRA volunteer Brendan "Ruby" Davison at his home in the Markets area of South Belfast on 25 July 1988 after receiving intelligence which revealed he had been Seymour's assassin.

In Frazer Pass there is a memorial plaque set inside a railed enclosure dedicated to Seymour, and he is also commemorated in many loyalist ballads and videos.
