Geography
The commune covers an area of. The eastern part of its territory lies within the fertile, central plain or "depresión intermedia", but the extense western part is hilly and somewhat drier, a typical "Cordillera de la Costa" terrain, which requires supplemental irrigation to support its varied cultivations. This area lends itself nicely to wine growing and cereal cultivation. Therefore, San Javier has some of the better vineyards and quality wines of the bountiful Maule Valley, in the Chile's central valleyviticultural regions or appellations. San Javier is bordered on the west by the communes of Constitución and Empedrado,, Cauquenes,, and Villa Alegre; on the north by Pencahue and Maule communes, in Talca province; on the east, by Yerbas Buenas, Villa Alegre, Linares and Longaví and on the south, by Cauquenes and Retiro. The town lies on the right margin of the River Loncomilla. Located a few km north of San Javier is the wide Maule river, of which the Loncomilla is the main tributary. River Purapel, a regional "anomaly", since it flows eastward in a country where the overwhelming majority of rivers flow in the opposite direction, is a tributary of the Loncomilla.

Heritage
Architecture
There are many villages and other smaller, rural entities within the communal territory; several of them are quite distant from the main urban centers and relatively isolated from the more distorting external cultural influences. Therefore, the commune can boast several villages with well-preserved colonial rural architecture - the criollo legacy - both in the religious as well as the civil domains. Singular examples of this brand of picturesque and bucolic villages, in the commune, are: Huerta de Maule, Nirivilo, Bobadilla, Caliboro and Melozal. Also, along the paved road that connects the towns of San Javier and Villa Alegre there are some outstanding examples of traditional Chilean rural architecture, which is especially noticeable in the farm houses typical of the region. Some of the parish churches in this zone are among the oldest in the Linares diocese and the Maule Region.
Poets
The Maule Region has produced a remarkable number of writers and poets and in consonancy with this legacy, San Javier has been the birthplace of two gifted poets: Raimundo Echeverría y Larrazábal and Jerónimo Lagos Lisboa.
