Karl Gerok (January 30, 1815 Vaihingen - January 14, 1890 Stuttgart) was a German preacher and religious poet.

His sermons, and particularly his religious poetry, were much admired.

The chief collection of the latter is entitled Palmblätter (“Palm leaves,” 1857; 17th ed., 1871).

This and Pfingstrosen (“Pentecost roses,” 4th ed., 1870) made him famous.

He also published Blumen und Sternen (“Flowers and stars,” 3rd ed., 1870) and, during the Franco-Prussian War of 1870-71, patriotic effusions under the title of Deutsche Ostern (“German Easter”).
