The Guzman Water Catchment is a historic private water supply structure in the rural Nalao area of the village of Barrigada in the United States territory of Guam. It is a roughly rectangular structure, measuring 4.4 by 2.84 by 1.52 metres (14.4 ft × 9.3 ft × 5.0 ft), with an open top. It is fashioned out of locally gathered stone joined with lime-cement mortar. It was built in 1910 by Baldobino Charfauros on family-owned land, and is one of the oldest surviving rural catchment basins on the island. It is further distinguished from other catchment basins in that it has a substantial floor. These types of structures made it possible for Guamanian families to live on rural holdings where water access was otherwise a significant problem.

The structure was listed on the National Register of Historic Places in 1994.
