'''NGC 2169''' 是一個位於[[猎户座]]的[[疏散星團]]，由於其外形近似於[[阿拉伯數字]]的37，而又被暱稱為'''37星團'''（The "37" Cluster）。NGC 2169最初由[[天文學家]][[威廉·赫歇爾]]於1784年10月15日首次確切紀錄到，但可能早在1654年前就已被[[義大利]]天文學家[[喬瓦尼·巴蒂斯塔·奧迪耶納]]發現<ref>{{cite book|last=O'Meara|first=S.

NGC 2169星團距離地球約3600光年，年齡估計約900萬年左右，是相當年輕的星團<ref name = Jefferies/>。<br />
