Dual Form (BH 396) is a bronze sculpture by the British artist Barbara Hepworth.
There is also a 19-inch bronze maquette (BH 397) which was cast in an edition of 9 plus an artist's copy.
An example of the full-size sculpture has usually been sited outside the St Ives Guildhall in Cornwall since 1966, but in 2024 it was temporarily moved to Kresen Kernow in Redruth while the area around the Guildhall is renovated.
Another full-size cast was bought by Leeds City Art Gallery in 1967, on loan to Leeds University since 2016.
Other casts are at the Peter Scott Gallery at Lancaster University, the Kröller-Müller Museum at Otterloo in the Netherlands, at The Phillips Collection in Washington DC (which also holds a maquette), and the Portland Art Museum in Portland, Oregon.
