Only if it is dishwasher safe. Check whether the manufacturer has labeled it dishwasher safe before attempting to put it in the dishwasher. With the exception of a few pans like Calphalon Nonstick Bakeware and Calphalon 1893302, pizza pans with nonstick coating should not be cleaned in the dishwater as this can damage the coating. The same is true for a lot of non-coated pizza pans, even cast iron ones. These should be hand-washed.
