Lympne (/lɪm/ ⓘ), formerly also Lymne, is a village on the former shallow-gradient sea cliffs above the expansive agricultural plain of Romney Marsh in Kent.

It had a Saxon Shore fort, and, according to a fifth-century source was garrisoned by a regiment originally raised in Tournai in northern Gaul.

[2] Its remains are at the bottom of the south-facing cliffs; they lie in private land but can be visited due to a public footpath crossing the area.

In the 1930s it was the starting point for several long-distance record flights, including a solo one to Cape Town by Amy Johnson in 1932, and also ones by her later-to-be husband Jim Mollison.

In the post-war years the world's first air car-ferry service was operated by Silver City Airways between Lympne and Le Touquet.

In H. G. Wells's 1901 novel First Men in the Moon, the English narrator Bedford, the sole survivor of the Moon expedition, attempts to land the antigravity sphere anywhere on Earth and has the good fortune to land it on the seashore at Lympne, reasonably close to his departure point.
