Dominguez Slough (American English pronunciation: slew or slu) was an endorheic lake and wetland in present-day Gardena, Los Angeles County, California, United States. Known for much of the late 19th century and early 20th century as Nigger Slough, it was renamed Lagunas de los Dominguez in 1938 in reference to the rancho-era Dominguez family. The slough was a "winding body of fresh water that wandered though Gardena and Carson on its way to the mud flats of San Pedro." Gardena is reportedly so named because "of the Laguna Dominguez slough and channel which in summer cuts a green swath across the barren brown landscape—an oasis in the drab, parched landscape between Los Angeles and the harbor area."

The Gardena Willows Wetland Preserve occupies 13.6 acres (55,000 m2) of land owned by the City of Gardena, in Los Angeles County, California. The preserve is the last intact remnant of the former Dominguez Slough, an important vernal marsh and riparian forest with riparian zones that once covered as much as 400 acres (1,600,000 m2) of this area, known as the South Bay region. The preserve has 9.4 acres (38,000 m2) of wetland and 4.2 acres (17,000 m2) of upland. The wetlands have a natural depression where water remains for such a significant time that plants and animals not adapted to water and saturated soils cannot survive. The upland, which remains dry outside of the rainy season, supports plants which thrive with these drier conditions. The slough is a part of the Dominguez Watershed, 96% of which is now covered with concrete and man-made structures. Located on the traditional lands of the Tongva, it is believed that these indigenous people were able to commute by canoe around much of the area. Tongva villages were located throughout much of what is now Los Angeles and Orange Counties as well as three southern Channel Islands (San Nicolas, San Clemente, Santa Catalina) as distant as 60 miles (97 km) from the coast of Los Angeles County.
