[[File:NGC 6281 map.png|thumbnail|圖中顯示NGC 6281的位置。]]

'''NGC 6281'''是位於[[天蝎座]]的一個[[疏散星團]]。它既不是[[梅西爾天體]]，也不是[[科德韋爾深空天體表|科德韋爾深空天體]]；但它是被排除在這兩個星表之外，在天蠍座中最亮的天體之一。它的位置在[[尾宿一]]東邊約2度，很容易以肉眼看見並觀察。[[詹姆士·敦洛普]]描述這個星團是一條"非常明亮的恒星的曲線，有許多星星混淆在一起"。[[約翰·赫歇爾]]後來描述這個集團為"非常明亮"和"非常富有" <ref name=crossen_rhemman2004/><ref name=omeara2007/>。

這個星團的潮汐半徑約為{{Convert|26|ly|pc|abbr=on}}，質量大約是214[[太陽質量]] <ref name=aaa477_1_165/>。它被歸類為II2p型，在距離中心20[[角分]]內有55顆[[視星等]]13.5等或更亮的恆星<ref name=aass61_45/>，最亮的成員是9等星。總體而言，這個星團的[[面亮度|集成視星等]]為5.4等<ref name=omeara2007/>。
