Gareth Jones (born 5 July 1961), also known as Gaz Top, is a Welsh television presenter.

In the summer of 2021 he became the first person to swim across Wales from south to north, whilst making a three-part documentary series for Welsh broadcaster S4C called Gareth Jones: Nofio Adre.

When he began his career in 1979, he used the name "Gaz Top", a name he earned whilst working as a roadie for The Alarm.

[5] Hosted by Jones, the show has an irreverent style and features a regular cast of Zog (AKA musician and journalist Paul Ireson) Richard Porter (creator of cult web-site Sniff Petrol and Script Editor previously of BBC's Top Gear and now of Amazon's The Grand Tour) and TV presenter and writer Violet Berlin.

He moved away from North London after an amicable separation[6] from his long-term partner, Violet Berlin.
