Heinrich Albertz (22 January 1915 – 18 May 1993) was a German Protestant theologian, priest and politician of the Social Democratic Party (SPD).

As a member of the Confessing Church opposing the Nazis, he showed solidarity with the imprisoned pastor Martin Niemöller, was arrested several times and finally conscripted into the Wehrmacht in 1941.

After World War II Albertz moved to Celle, where the British occupation authorities entrusted him with the reception of expellees and displaced persons.

Albertz, standing in the shadow of his popular predecessor, led the Social Democrats into the following state election held on 12 March 1967.

When on 27 February 1975 the Movement 2 June militant group (named after the obit of Benno Ohnesorg) abducted the Christian Democrat candidate for Mayor of West Berlin Peter Lorenz, Albertz agreed to accompany the exchanged prisoners, among them Verena Becker and Gabriele Kröcher-Tiedemann, on their flight to South Yemen.
