RAF Hell's Mouth is a former Royal Air Force Emergency Landing Ground at Hell's Mouth, (Porth Neigwl) on the Llŷn Peninsula near Abersoch, Gwynedd, Wales.

RAF Hell's Mouth was commissioned in February 1937 as a Relief Landing Ground, later an Emergency Landing Ground for RAF Penrhos. It was also an air gunnery and bombing range, with targets on the land, floated 1 mile offshore and towed drogues in the air. A small range railway was in use to provide moving targets.

Typical aircraft using the airfield were Bristol Blenheim and Armstrong Whitworth Whitley. In August 1944 a Vickers Wellington was successfully landed by a Polish pilot following an engine failure. Despite the mismatch in size, the aircraft also was able to subsequently take off.

No. 9 (Observers) Advanced Flying Unit RAF was posted here at some point.

The site was decommissioned in 1945 and returned to agriculture.
