Sedimenticolaceae is a family of bacteria of the order Chromatiales within the Gammaproteobacteria. The family was proposed upon the discovery of Sedimenticola hydrogenitrophicus in samples isolated from a terrestrial mud volcano.

Like other Proteobacteria, the Sedimenticolaceae are Gram-negative and some members are chemolithoautotrophic (similar to the Halothiobacillaceae and Thioalkalibacteraceae).
