A reverse __ortho__ effect is observed for the ^13^ C NMR chemical shifts of the carboxyl carbon (__δ__~co~) in benzoic acids measured in aprotic solvents of varying polarity. The __ortho__ effect on __δ__~co~ is best described by a combination of the reverse field and steric accelerating effects of
