Giovanni Demisiani (Greek: Ἰωάννης Δημησιάνος; died 1614), a Greek from Zakynthos, was a theologian, chemist, mathematician to Cardinal Gonzaga, and member of the Accademia dei Lincei. Demisiani is noted for coining the name telescope (from the Greek , tele "far" and , skopein "to look or see") for a version of the instrument presented by Galileo Galilei to the Accademia dei Lincei at a banquet honoring Galileo’s induction into the Accademia in 1611.
