Background: Coffee has a stimulant nature for which it is consumed worldwide, especially in Indian subcontinent. It also contains various antioxidant and antibacterial properties and is good for health.

Aims and Objectives: This study done in tertiary care teaching hospital, aims to assess the antibacterial activity of coffee extract in surgical wound infections.

Materials and Methods: The antibacterial activity of coffee extract against pathogenic bacteria (Gram-positive and Gram-negative) isolated from the surgical wounds was tested.

Results: Both Gram-positive and Gram-negative bacteria were found sensitive to the methanol coffee extract.

Conclusion: Our study revealed that coffee extract can be used in the future as a substitute antimicrobial for the treatment of pathogenic bacteria due to its wide antimicrobial activity and we suggest advanced study on coffee extract to explore the bioactive compounds accountable for the detected antimicrobial activity.

Key words: Coffee; Minimum Inhibitory Concentration; Minimum Bactericidal Concentration; Antimicrobial Activity
