Sidcot Swallet is a cave near Burrington Combe, in the Carboniferous Limestone of the Mendip Hills, in Somerset, England.

It was named after the Sidcot School Speleological Society who explored it in 1925.{{cite book|last=Witcombe|first=Richard|title=Who was Aveline anyway?: Mendip's Cave Names Explained|year=2009|publisher=Wessex Cave Club|location=Priddy|edition=2nd|page=161|isbn=978-0-9500433-6-4}}

A swallet, also known as a sinkhole, sink, shakehole, swallow hole or doline, is a natural depression or hole in the surface topography caused by the removal of soil or bedrock, often both, by water flowing beneath.

After Goatchurch Cavern, Sidcot Swallet is probably the most popular cave on Mendip for novice parties. What it lacks in length or depth is adequately compensated for by its sporty squeezes and narrow crawls. Despite its popularity, many calcite formations still remain intact in the farthest reaches of the cave.{{cite book |last1=Irwin |first1=David |first2= Anthony |last2=Knibbs|title=Mendip Underground: A Cavers Guide |year=1977 |publisher=Mendip Publishing |location=Somerset |isbn=0-9536103-0-6}}
