Wheal Owles (Cornish: Hwel Als) was a tin mine in the parish of St Just in Cornwall, UK and the site of a disaster in 1893 when twenty miners lost their lives.

The mine is within the Aire Point to Carrick Du Site of Special Scientific Interest (SSSI) and the South West Coast Path passes along the cliff.

As water rushed into Wheal Owles the air blasted through the mine blowing out the lights and leaving the miners in darkness.

Knowing that something had gone wrong in the mine, the men made for the ladders, and soon found out it was a case of hurry and strain every nerve for life or death.

"The result is that the immense pool of water now stretched through, practically, three mines and is a mile-and-a-half in length - almost from the sea to beneath the Wesleyan Chapel at St Just Church-town."
