Heinrich Gottlieb Tzschirner (14 November 1778 – 17 February 1828) was a German Protestant theologian born in Mittweida, Saxony.
He studied theology at the University of Leipzig, receiving his habilitation in 1800 with assistance from Dresden examinator Franz Volkmar Reinhard (1753-1812).
For a period of time he worked as a private lecturer at the University of Wittenberg, and following his father's death became deacon in his home town of Mittweida.
As a theologian, Tzschirner was an advocate of ethical and critical rationalism, believing that common sense morality was the supreme principle of Christianity.
In one of his better known works, Protestantismus and Katholicismus aus dem Standpunkte der Politik betrachlet, he staunchly defended the Protestant cause versus Catholicism.
