Martin Zeiler (also Zeiller, born 17 April 1589 in Ranten, died 6 October 1661 in Ulm) was a Baroque era German author.

Zeiler's father was an exile from Upper Styria, forced to emigrate due to his protestant confession.

Zeiler was schooled in Ulm, moving to Wittenberg in 1608 to study jurisprudence and history.

The Ulm city library lists 90 works authored by Zeiler.

His productivity was recognized by his contemporaries; Georg Philipp Harsdörffer mentions Herrn Zeillers proverbial industriousness in one of his poems.
