A '''sluice''' ({{IPAc-en|s|l|u|s}} {{respell|SLOOS}}) is a [[Channel (geography)|water channel]] containing a '''sluice gate''', a type of [[Lock (water navigation)|lock]] to manage the water flow and water level. There are various types of sluice gates, including flap sluice gates and fan gates. Different depths are calculated when design sluice gates.

Sluices are used for channeling water toward a [[water mill]], including for transporting logs from steep hillsides. Different terms are used regionally for sluices; the terms ''sluice'', ''sluice gate'', '''''knife gate''''', and '''''slide gate''''' are used interchangeably in the water and [[wastewater]] control industry.
