Horace Gray Lunt (September 12, 1918 – August 11, 2010) was a linguist in the field of Slavic Studies. He was Professor Emeritus at the Slavic Language and Literature Department and the Ukrainian Institute at Harvard University.

Born in Colorado Springs, Lunt attended Harvard College (BA 1941), the University of California (MA 1942), Charles University in Prague (1946–47), and Columbia University (PhD 1950).^[1][2] As a student of Roman Jakobson at Columbia, he joined the Harvard University faculty in 1949 together with his mentor.^[1] There he taught the course on Old Church Slavonic grammar for four decades, creating what has become the standard handbook on it, now in its seventh edition.

He published numerous monographs, articles, essays, and reviews on all aspects of Slavic comparative and historical linguistics and philology. A notable part of his work was devoted to establishing Macedonian as an independent language.^[1] In the early 1950s, sponsored by the Yugoslav Ministry of Science, Lunt authored the first English language grammar of Macedonian.^[3][4]
