Karl Ludwig Lehrs (January 14, 1802 – June 9, 1878), was a German classical scholar.
His most important works are:
- De Aristarchi Studiis Homericis (1833), which laid a new foundation for Homeric exegesis (on the Aristarchean lines of explaining Homer from the text itself) and textual criticism.
- Quaestiones Epicae (1837).
- De Asclepiade Myrleano (1845).
- Herodiani Scripta Tria emendatiora. Accedunt Analecta (1848).
- Populäre Aufsätze aus dem Altertum (1856, Second much enlarged edition, 1875), his best known work.
- Horatius Flaccus (1869), in which, on aesthetic grounds, he rejected many of the odes as spurious.
- Die Pindarscholien (1873).
Lehrs was a man of decided opinions; his enthusiasm for everything Greek caused him to insist on the undivided authorship of the Iliad; comparative mythology and the symbolical interpretation of myths he regarded as a species of sacrilege.
- The three treatises which are the object of this study are Περὶ μονήρους λέξεως, Περὶ Ἰλιακῆς προσωιδίας, and Περὶ διχρόνων.
