O Grove (alternative spelling: Ogrobe) is a municipality belonging to the province of Pontevedra, in Galicia, Spain.

A peninsula that faces the Atlantic Ocean and the shores of O Salnés valley, enclosed by the southern Galician estuaries, the Rías Baixas.

The name Ogrobe is well documented and the following passage in Latin was written about the name of Ograbe: "et ecclesiam Sancti Uincentii in insula Ocobre dextris cum suis." (899, St. Vincent of O Grove). Its original form is Ogrobe, having suffered in more recent times as a result of a completely Spanish etymological process. As natural etymological evolution occurred, the segmentation of the initial vowel "O" was confused with the masculine singular article in Galician and is translated as "El" in Spanish.
