Gravimetric method has been used to study the effect of Aqueous extract of Fenugreek seed (AEFS) on the corrosion of Iron in Citric Acid solutions. The percentage inhibition increased with the increase of the concentration of the inhibitor in the studied range. The inhibition efficiency decreases with increase in temperature. The adsorption of AEFS on Iron surface obeys the Langmuir adsorption isotherm and the kinetic parameters for the adsorption of this inhibitor on the metal surface are calculated by using the Arrhenius equation. The Aqueous extract of Fenugreek seeds is observed as a good corrosion inhibitor in Citric Acid solutions at experimental conditions
