Сан-Исидро муниципалитеті, Филиппиннің Давао Ориентал провинциясы

Municipality in Davao Oriental, Philippines

San Isidro, officially the Municipality of San Isidro (; ), is a 3rd class municipality in the province of Davao Oriental, Philippines. According to the 2020 census, it has a population of 33,664 people. San Isidro is one of the "gulf towns" of Davao Oriental whose shorelines stretch along Davao Gulf. Other gulf towns are Banaybanay, Lupon and Governor Generoso.

The town of San Isidro was created by virtue of Republic Act No. 4744 enacted by the Philippine Congress on June 18, 1966. It started operating as a local government unit in January 1968. Its founder and the first mayor was Vicente Yu, Sr.

San Isidro is politically subdivided into 16 barangays. Each barangay consists of puroks while some have sitios. Seven barangays are along the coastlines while the other nine are in the interior areas.

Around 30% of the population belong to the indigenous Mandaya and Kalagan communities.

San Isidro is largely planted with coconut, with much of its agricultural industry focuses on the production of copra. There are currently efforts to further diversify the output of the municipality's coconut based industry from copra to other value added coconut products such as coco oil (which can be used as a fuel additive) and coco coir. In 1992, a Crop Diversification Program of the local government unit (LGU) was implemented with mango as "export winner". In 1998, the town commenced its first Mango Festival as an indicator of the prominence of this high yielding fruit. Farmers are also engaged in growing the popular banana (cardava). Despite this, farmers still experience difficulties in increasing their income due to lack of agricultural technology specially those farming in the upland areas. The aggressive anti illegal fishing efforts of the LGU decreased dynamite fishing and able to establish fish sanctuaries in San Isidro waters. Most of the fishermen in this town used paddle boat than motorized boat in fishing.
