Corrosion inhibition of mild steel (MS) by aqueous extract of Lantana camara L. leaves (AELCL) has been studied by gravimetric method at different temperatures. The results revealed that inhibition efficiency increases with increase in inhibitor concentration and decreases with increase in temperature within the studied range of concentrations and temperatures. Adsorption of extract at mild steel surface follows Langmuir adsorption isotherm. Maximum inhibition efficiency of 90% was observed with 6% (v/v) concentration of inhibitor at 30^oC.
