Acetobacteraceae is a family of Gram-negative bacteria, belonging to the order Rhodospirillales, class Alphaproteobacteria.

Two distinct clades are recognized: the acetic acid bacteria and a more heterogeneous group including acidophilic and phototrophic bacteria.

[2] Ten genera from Acetobacteraceae make up the acetic acid bacteria.

[3] Acetobacteraceae was originally proposed as a family for Acetobacter and Gluconobacter based on rRNA and DNA–DNA hybridization comparisons in 1980.
