'''IC 342'''是位於[[鹿豹座]]的一個[[中間棒旋星系|中間螺旋星系]]，它的位置很接近[[銀道座標系|銀河赤道]]，因此受到塵埃的遮蔽，無論業餘或專業的天文學家都難以觀測到它<ref name="ned" />。

IC 342是在[[馬菲星系群]]中最明亮的兩個星系之一，這是很靠近[[本星系團]]的一個[[星系團]]。這個星系是[[威廉·弗雷德里克·丹寧]]在1895年發現的。[[愛德溫·哈伯|哈伯]]最早認為它是[[本星系團]]的成員，但稍後的證據顯示它是在本星系團之外<ref>SEDS [http://www.seds.org/~spider/spider/LG/i0342.html IC 342] {{Wayback|url=http://www.seds.org/~spider/spider/LG/i0342.html |date=20070102030726 }}.</ref>。

它有一個[[電離氫區|HII]]的核<ref name="hoetal1997">{{citation
