Weiss is an unincorporated community in Livingston Parish, Louisiana, United States.

The community is located less than 3 miles (4.8 kilometres) southwest of Baywood and 6 miles (9.7 kilometres) northeast of Watson near the Amite River.

In 1894 a local man named Fred Nesom and his father Henry Nesom began organizing the community and sought the help of a German man named Fred Weiss who was the postmaster in the nearby community of Fred, Louisiana.

The post office was closed sometime in April 1949.
