Frankia is a genus of nitrogen-fixing bacteria that live in symbiosis with actinorhizal plants, similar to the Rhizobium bacteria found in the root nodules of legumes in the family Fabaceae. Frankia also initiate the forming of root nodules.

This genus was originally named by Jørgen Brunchorst, in 1886 to honor the German biologist Albert Bernhard Frank.[4] Brunchorst considered the organism he had identified to be a filamentous fungus. Becking [de; nl] redefined the genus in 1970 as containing prokaryotic actinomycetes and created the family Frankiaceae within the Actinomycetales. He retained the original name of Frankia for the genus.[5]
