蹼泳是一种新兴运动，指利用腰腹摆动前进的泳术，足部则须戴上蹼，有时也会配合其他适当器材（如呼吸器），而泳姿就像海豚一样。

蹼泳主要分为三大类，包括水面蹼泳、闭气潜泳及器泳。

• 水面蹼泳：最基本的蹼泳，利用呼吸器呼吸，赛程分为50、100、200、400,800及1500米
• 闭气潜泳：不能用呼吸器，故需要闭气潜入水中一口气游完全程，赛程50米
• 器泳：需要双手伸直，并握着压缩氧气筒，利用口吸气、鼻呼气，赛程分为100、400及800米
• 双蹼: 基本和自游泳相同赛程分为50,100,200米

Finswimming is an underwater sport consisting of four techniques involving swimming with the use of fins either on the water's surface using a snorkel with either monofins or bifins (i.e. one fin for each foot) or underwater with monofin either by holding one's breath or using open circuit scuba diving equipment. Events exist over distances similar to swimming competitions for both swimming pool and open water venues. Competition at world and continental level is organised by the Confédération Mondiale des Activités Subaquatiques (CMAS). The sport's first world championship was held in 1976. It also has been featured at the World Games as a trend sport since 1981 and was demonstrated at the 2015 European Games in June 2015.
