Sir George Grove, CB (13 August 1820 – 28 May 1900) was an English writer on music, known as the founding editor of Grove's Dictionary of Music and Musicians.

Grove was trained as a civil engineer, and successful in that profession, but his love of music drew him into musical administration. When responsible for the regular orchestral concerts at the Crystal Palace, he wrote a series of programme notes from which eventually grew his musical dictionary. His interest in the music of Franz Schubert, which was neglected in England at that point in the nineteenth century, led him and his friend Arthur Sullivan to go to Vienna in search of undiscovered Schubert manuscripts. Their researches led to their discovery of the lost score of Schubert's Rosamunde music in 1867.
