This paper reports a simple and rapid method for simultaneous determination of the residues of selected herbicides viz. pendimethalin, oxyfluorfen, imazethapyr and quizalofop-p-ethyl in peanut by liquid chromatography-tandem mass spectrometry (LC-MS/MS). A modified approach of the QuEChERS methodology was used to extract the herbicides from the peanut kernel without any clean-up. The method showed excellent linearity (r2 > 0.99) with no significant matrix effect. Accuracy of the method in terms of average recoveries of all the four herbicides ranged between 69.4 –94.4 % at spiking levels of 0.05, 0.10 and 0.25 mg kg−1 with intra-day and inter-day precision RSD (%) between 2.6–16.6 and 8.0–11.3, respectively. Limit of quantification (LOQs) was 5.0 μg kg−1 for pendimethalin, imazethapyr and quizalofop-p-ethyl and 10.0 μg kg−1 for oxyfluorfen. The expanded uncertainties were
