The Finfoots (Heliornithidae) are a small family of three species of tropical birds with webbed lobes on their feet like those of grebes and coots.

Finfoots resemble rails; they have long necks, slender bodies, broad tails, and sharp, pointed bills. They have a diverse range of calls, but do not call frequently. Their legs and feet are brightly coloured and, unlike grebes, they are capable of walking well and even moving quickly on land. Finfoots are found in numerous habitats in the tropics as long as there is water and cover. It is uncertain why cover is so essential to finfoots, but they are extremely secretive and often overlooked.

Finfoots feed on a wide range of foods, insects of various sorts being the most frequently observed component of their diet. Unlike grebes they do not dive to obtain food, instead picking prey off the water's surface or foraging on the shore.
