"Itsy Bitsy Spider" (also known as "Incy Wincy Spider" and several other similar sounding names) is a popular nursery rhyme and fingerplay that describes the adventures of a spider as it ascends, descends, and reascends the downspout or "waterspout" of a gutter system (or, alternatively, the spout of a teapot or open-air reservoir). It is usually accompanied by a sequence of gestures that mimic the words of the song. Its Roud Folk Song Index number is 11586.
