Ash Kilmartin is an artist from Aotearoa/New Zealand, currently based in the Netherlands. She works in sculpture and performance, with ongoing projects in sound, broadcast and publishing as modes of collaboration and distribution.

Her recent work is concerned with the speaking voice as tool for finding and making public space.
Her work addresses the way the voice operates the distinction between private and public; being the hinge between the physical material of the body, and the social fabric of language. She is interested in gendered characterisations of the speaking body; in non-linguistic vocalisations as communication; and in how the voice can be translated into orthography, texture, or space.

Ash holds an MA from the Piet Zwart Institute, Rotterdam and BFA(Hons)/BA from the University of Auckland. She has presented work at KIOSK, Ghent; De Player, Rotterdam; ACCA, Melbourne and the Physics Room, Christchurch, among others.
