The antimicrobial activities and the antioxidant properties of the ethanolic root extract of Tamarindus indica L., were carefully analyzed using standard methods. The antimicrobial activities of ethanolic root extract of T. indica L., was assessed on some bacterial isolates such as Escherichia coli, Staphylococcus aureus, Proteus mirabilis and Pseudomonas aeruginosa to estimate the inhibition zone in mm, using agar diffusion method. The Total antioxidant capacity of the ethanolic root extract of Tamarindus indica L., were carefully analyzed using the standards of Vitamin C Equivalent (VCE) and Gallic Acid Equivalent (GAE). The result revealed that ethanolic root extract of Tamarindus indica L., has antimicrobial properties as shown by its activity on test bacterial strains. The activity of the plant extract varied with concentration (mg/ml) of the ethanolic extract of T. indica. At 5.00 mg/ml of extract, S. aureus was the most susceptible to the ethanol extract of T. indica, while the least susceptible was E. coli. The Total antioxidant capacity (mg VCE) revealed a maximum and minimum value of 109.57 and 109.17, Total phenolic content (GAE100g-1) 64.04 and 61.84, and Total Ascorbic content (mg/kg) 278.64 and 278.04 respectively. The result revealed that ethanol root extract had antimicrobial properties as shown by its activity on test bacterial strains. The total antioxidant capacity detected were within a reasonable range. The presence of the secondary metabolites in the root extract of T. indica L., is perhaps the reason for its medicinal properties.\
