Arin Dwihartanto Sunaryo (b. 1978) is an artist based in Bandung, Indonesia. He studied painting at Institut Teknologi Bandung (2001) and Central Saint Martins, London (2005). Arin works with painting as an expanded medium. In it, his practice pertains to qualitative difference carried by both the imagerial and the material in painting.

Working often with resin and pigments, as well as canvas and paint, Arin explores the plasticity of how pictures are painted. His practice can be associated with the almost choreographic aspect of action painting. His choice of colouring, however, is collected from various materials associated with everyday life and issues occurring.

Things are ground down to become pigment: ash from an erupting volcano, palm-oil fruits of converted lands, instant ramen, deep-fried egg, and montages of prints. Afloat the paintings, they depict the multiplicity and mobility of matter. Arin's paintings come together not as mere frozen movement of colour spectra, but as narratives relational to the formation of our vision in the now-time.

His works have been featured in exhibitions such as No Country: Contemporary Art for South and Southeast Asia, Solomon R. Guggenheim Museum, New York (2013); Silent Salvo, ARNDT Berlin, Germany (2015, solo show); after taste, Sullivan + Strumpf, Sydney, Australia (2017, solo show); Argo, Simon Lee Gallery, London, United Kingdom (2019, solo show); External Entrails, Silverlens, New York (2023); Base Matters, Selasar Sunaryo Art Space Bandung, Indonesia (2023, solo show); and is part of the public collection of the Solomon R. Guggenheim Museum, New York, United States.
