Friedrich Ludwig von Keller (17 October 1799, in Zürich – 11 September 1860, in Berlin) was a Swiss-German jurist.
He was educated at Berlin and Göttingen, where he was a pupil of Savigny. In 1825, he returned to Zürich where he was appointed professor of civil law in the university. He was a leader of the Liberal Radical party and in 1831 became head of the Swiss justiciary. In 1843-47 he was professor in the University of Halle. He then moved to Berlin, where he became professor at the university. He became a conservative member of the Prussian House of Representatives, and because of his services to the monarchical party was ennobled.
His Vorlesungen über die Pandekten was edited by Emil Albert Friedberg (1861), and by William Lewis (1867).
