Yeovil Grammar School was a grammar school in Yeovil, Somerset, which was founded or refounded about 1860 and closed in 1906 when its only headmaster, Henry Monk, retired.
The 19th-century grammar school grew out of a long-established charity school, which according to some sources was itself a grammar school when founded in 1573 and was referred to by that name in 1839 and 1853.
