Gustav Benjamin Schwab (19 June 1792 – 4 November 1850) was a German writer, pastor and publisher.

While at university he established a literary club and became a close friend of Ludwig Uhland, Karl Varnhagen and Justinus Kerner, with whom he published a collection of poems under the title Deutscher Dichterwald.

In 1818 he became a high school teacher in Stuttgart, and in 1837 he started work as a pastor in Gomaringen, near Tübingen.

Schwab's collection of myths and legends of antiquity, Sagen des klassischen Altertums, published from 1838 to 1840, was widely used at German schools and became very influential for the reception of classical antiquity in German classrooms.

In his later years, he traveled regularly to Überlingen am Bodensee to enjoy the waters at the city's spa.
