We present the internal and foreground reddening maps of the Large and Small Magellanic Clouds. These are estimated using the red clump stars identified from the OGLE III catalog. The foreground reddening is estimated from the shift of the peak in the red clump colour distribution and the internal reddening from the width of the colour distribution, after correcting for population effects. The foreground reddening in the LMC is found to be correlated with the location of the star forming regions. The reddening towards the LMC is found to be larger than that towards the SMC.
