The Australia Telescope Compact Array (ATCA) has been used to make the first full polarization observations of 6.7 GHz methanol masers. Linear polarization was detected towards all four sources observed, at levels between a few and 10%, while none of the sources show circular polarization stronger than approximately 1.5%. Linear polarization appears to be more common in the 6.7 GHz methanol maser transition than it is for the 12.2 GHz transition, consistent with the hypothesis that the 6.7 GHz masers are more saturated.
