The IRAS Point Source Catalog has been searched for infrared sources associated with G-type stars. Of the 3803 IRAS sources identified in this way, 28 were found to have enhanced emission at lambda greater than 25 microns characteristic of circumstellar material. The majority of the IR-excess stars were supergiants whose inferred mass loss rates were found to be comparable to those of red giants. One of the stars, IRAS 11059-7721, is a G main-sequence star whose circumstellar medium (CSM) has 20,000 times the optical depth of Vega's CSM. The physical characteristics of the circumstellar emission for this sample are described, and several scenarios for its existence are examined in light of the IRAS data.
