Roberts Landing was a settlement in Alameda County, California, now incorporated into the town of San Leandro. It is located at the mouth of San Lorenzo Creek on San Francisco Bay just west of the community of San Lorenzo. In the 19th century, it had warehouses and a wharf, and was used by farmers to ship their produce to the city of San Francisco. From 1906 to 1964, it was the site of an explosives manufacturing plant operated by the Trojan Powder Company. Following the plant's closure, the site was decontaminated. After protracted discussions, part was made into a housing development while a larger part was made an open space that is now also called the San Leandro Shoreline Marshlands.
