George Edmund Lindsay (1916 – 2002) was an American botanist, naturalist, and museum director. From 1956 to 1963, he was director of the San Diego Natural History Museum and served as Director of the California Academy of Sciences from 1963 to 1982. At both institutions, Lindsay led research field expeditions to the islands in the Sea of Cortez (Vermilion Sea and Gulf of California) found between the Baja California Peninsula and mainland Sonora, Mexico. These expeditions relied on the Vermilion Sea Field Station at Bahia del Los Angeles as their base of operations, which he facilitated and organized. He was active in trans-national conservation efforts to protect the islands as biodiversity sanctuaries in the Gulf of California.
