Widdows Island is a small island in the Sacramento–San Joaquin River Delta along the Old River distributary of the San Joaquin River. It is part of San Joaquin County, California. Its coordinates are {{coord|37|51|40|N|121|34|27|W|region:US-CA_source:gnis-237725|display=inline|name=Widdows Island|notes=}}, and the United States Geological Survey measured its elevation as {{cvt|0|ft|m}} in 1981. It appears on USGS maps of the area as dry land up to 2018; the latest 2021 topographic map shows the island now mostly flooded, with the old levee surrounding it still above water.
