Wilhelm Freund (January 27, 1806 – June 4, 1894) was a German Jewish philologist, born at Kępno.

He received his education at Berlin and Breslau, and was chiefly occupied in teaching until 1870, when he retired in order to devote himself to his literary pursuits. Besides classical school-books and some works on philology, he compiled an elaborate Latin dictionary in 4 volumes, the Wörterbuch der Lateinischen Sprache (1834–45), which has been the basis of the standard English-Latin dictionaries in the 19th century. It was translated into English by Ethan Allen Andrews in 1850 and revised (with Freund's own assistance) as the basis for Lewis and Short's A Latin Dictionary. He also wrote:

• Wie studiert man Philologie (sixth edition by Dieter, Stuttgart, 1903).
• Tafeln der Litteraturgeschichte (1877).
• Triennium Philologicum (third edition, 1906 et seq.).
• Präparationen zu den griechischen und römischen Klassikern, (a long work beginning in 1859)
• Wanderungen auf klassischem Boden (1889–92).
