Glass Art One is a collection of autonomous stained glass panels featuring constructivist landscapes and produced by Brian Clarke between 1974 and 1975.

The collection includes two untitled panels, Glass Art One (1), Glass Art Two (2), as well as The Aspinall and The Flying Childers windows, both of which were subsequently installed in private venues.

The series was first exhibited in 1975 as part of the travelling exhibition Glass Art One.
