Johan Bara (or Barra) (c. 1581 – 1634) was a Dutch painter, designer and engraver.
He was born in Den Bosch or Middelburg, and first worked in Holland, went then to England, where he died in 1634. He called himself, sometimes, "sculptor et vitrearum imaginum pictor", and published, from 1598 to 1632, several engravings which resemble, without equalling, those of Aegidius Sadeler. His first plate, "Susanna in the Bath", signed Barra (1598), is very rare. His plates are numerous.
