Ernst Friedrich Kärcher (4 August 1789 – 12 April 1855) was a German educator and philologist born in Ichenheim, a village in Baden-Württemberg.
He is remembered as an author of numerous Latin dictionaries.
He studied theology and classical languages at the University of Heidelberg, and subsequently worked for several years as a tutor.
In 1815 he became a teacher at the Pädagogium in Durlach, and in 1820 was an instructor at the Lyceum Karlsruhe, where he taught classes until his death in 1855.
Kärcherstraße, a street in the Mühlburg district of Karlsruhe is named in his honor.
