In the Revised and Updated Catalog of Quasi-Stellar Objects of Hewitt \& Burbidge, 1993, 90 sources are designated as BL Lacertae objects, out of which 11 have redshifts lower than 0.1. One of these 11 nearby BL Lacertae objects, Mrk 501, is too close to the bright EGRET detection of 1633+382 to be analyzed properly in the EGRET data. Another one, BL Lacertae, is situated very close to the galactic plane; the galactic diffuse emission will mask any extragalactic source with flux level comparable to a typical high-latitude EGRET detection. For the remaining 9 nearby BL Lacertae objects, EGRET has detected 3 of them during Phase 1 and Phase 2 of the Compton Observatory's viewing program. The duty cycle of EGRET detection of a nearby BL Lacertae object, calculated from the ratio of the total expoure time during which EGRET has a detection to the total exposure time of the overall coverage of this sample of 9 sources by EGRET, is found to be about 30%. For the other 6 undetected nearby BL Lacertae objects in this sample, co-adding of the EGRET data also yields no detactable flux. These EGRET results will be discussed in the paper.
