David Ruben Piqtoukun (born 1950) is an Inuit artist from Paulatuk, Northwest Territories. His output includes sculpture and prints; the sculptural work is innovative in its use of mixed media. His materials and imagery bring together modern and traditional Inuit stylistic elements in a personal vision. An example of this is his work "The Passage of Time" (1999), which portrays a shaman in the form of a salmon moving through a hole in a hand. While shamanic imagery is common in much of Inuit art, the hand in this work is sheet metal, not a traditional material such as walrus ivory, caribou antler or soapstone. Ruben's brother, Abraham Apakark Anghik Ruben, is also a sculptor. Fellow Inuit artist Floyd Kuptana learned sculpting techniques as an apprentice to David Ruben.
