Lucas Bacmeister (18 October 1530 – 9 July 1608) was a Lutheran theologian and church music composer.

On the recommendation of Philip Melanchthon he then went on to Rostock where at Easter 1562 he took over the post of Superintendent, simultaneously also becoming a Teacher/Professor of Theology at the university.

[1] In the context of the intensification of the political tensions arising from the Reformation, the exercise can be seen as part of a larger push to counter the rise of Flacian fundamentalism.

Later he also controlled the final version of the Mecklenburg Church Ordinance of 1602, after its original author, David Chytraeus, left it incomplete when he died in 1600.

Bacmeister had also produced, in 1577, the Rostock Hymnal which opened the way for Joachim Burmeister church music publications.

Bacmeister's own hymn "Ach leue Her im höchsten thron" appeared in 1565 during the depths of the Rostock plague outbreak.

[5] After his first wife died Lucas Bacmeister married Katharina Beselin (1536–1593), widow of the Rostock municipal leader Johannes Herverden.
