'''M105'''（也稱為'''NGC 3379'''）是一個位於獅子座的[[橢圓星系]]，由[[皮埃爾·梅香]]（Pierre Méchain）於1781年3月24日所發現。M105擁有一個[[超大質量黑洞]]。

M105也是獅子座I星系群（即[[M96星系群]]）中的一個星系，此星系群中還包括[[M95 (棒旋星系)|M95]]與[[M96]]兩個梅西耶天體。

M105星系和伴星系[[NGC 3384]]（透鏡星系）被一個巨大的[[中性氫]]環所包圍，該環半徑為200千秒差距（650千光年），質量為{{Val|1.8|e=9|ul=solar mass}}，科學家在該環上已探測到[[恆星]]形成<ref name="thilker2009">{{cite journal
