This study examined patterns of alcohol use and its association with unsafe sex and related sequelae among female sex workers in Mombasa, Kenya. A community-based cross-sectional study was conducted using snowball sampling. Binge drinkers (≥5 alcoholic drinks on ≥1 occasion in the previous month) were compared with non-binge drinkers. Of 719 participants, 22.4% were lifetime-alcohol abstainers, 44.7% non-binge and 33.0% binge drinkers. Compared with non-binge drinkers, binge drinkers were more likely to report unprotected sex (adjusted odds ratio (AOR)=1.59, 95% confidence interval [CI]=1.00–2.53; P=0.047) and sexual violence (AOR=1.85, 95% CI=1.27–2.71; P=0.001) and to have either syphilis, Neisseria gonorrhoeae or Trichomonas vaginalis infection (AOR=1.56, 95% CI=1.00–2.41; P=0.048). HIV prevalence was higher among women having ever drunk (39.9%) than lifetime abstainers (23.2%; P
