Bertha is an unincorporated community in Dale County, Alabama, United States.
Bertha is likely named in honor of the daughter of the post master.[2] A post office operated under the name Bertha from 1891 to 1904.[3]
Bertha is also the site of an annual food, music, and entertainment festival known as the "Bertha Pig Roast." Held each March, the event began as a small cookout in 1996, but it has grown into a weekend-long extravaganza featuring the local food, music, art, and history of the Bertha community.
