Bog snorkelling is a sporting event that consists of competitors completing two consecutive 60 yards (55 m) lengths of a water-filled trench cut through a peat bog in the shortest time possible. Competitors must wear snorkels and flippers and complete the course without using conventional swimming strokes, relying on flipper power alone. A wetsuit is not compulsory, but is often worn.

The activity of bog snorkelling was started in 1976 near Llanwrtyd Wells, Wales, United Kingdom. It began as a result of an over-the-bar conversation in The Neuadd Arms between Gordon Green and a few regulars.

The World Bog Snorkelling Championship, first held in 1985, takes place annually every August Bank Holiday at the dense Waen Rhydd peat bog, near Llanwrtyd Wells in mid Wales. In 2014 Kirsty Johnson broke the previous world record set by Dineka Maguire in 2013. Kirsty's time was 1:22.56 secs. The world and men's champion for 2016 is Neil Rutter in a time of 1 min 26.15 secs The ladies' champion 2017 Jess Fidler 1 min 41.87 secs . Paddy Lambe, the 2016 Irish champion set a time at the Irish Bog Snorkelling Championships in September 2016 of 1:19 which set a new world record for bog snorkelling. The Irish event in 2016 was also the first time a brother and sister won the national championship in the same year. Moira Lambe, Paddy's sister, won the ladies' event in the same year.
