Weed Heights is an unincorporated community in Lyon County, Nevada, USA. It is adjacent to Yerington.
The Anaconda Copper Company built Weed Heights in the 1950s to support the Anaconda Mine. The town was owned by Anaconda until the company was taken over by Atlantic Richfield Company. Atlantic Richfield ceased operations in 1978 and sold the property in 1982 to Don Tibbals, a Lyon County commissioner, who subsequently sold the entire property to Arimetco, with the exception of the town of Weed Heights, which is now a rental community and RV park.
