狐狸座OB1是一个在其中诞生了一批大质量恒星的OB星协。它最早是由W.W.摩根（1953年）等人确认的^[4]。该星协位于猎户臂，距离太阳大约7,500光年^[5]。包含在这个星协中的星云包括NGC 6820和NGC 6823^[4]，以及 Sh2-88^[5]。

狐狸座OB1包含近100颗OB型恒星和800多颗年轻恒星天体。该星协长约100秒差距，且均匀形成。这个年轻恒星天体以两个群体的形式存在，一个群体代表孤立的年轻恒星天体，另一个群体包括红外星云。在Sh2-86、Sh 2-87、Sh 1-88、致密HII区和其它星团，例如Cr 404周围，都有很多年轻恒星天体的族群。这被怀疑是由触发的恒星形成引起的。OB型恒星在这个区域塑造了许多柱状结构^[6]。
