武仙座2021年新星，也称为武仙座V1674，是在星座武仙座出现的一颗新星。它在星等的峰值亮度达到了6.0等，在理想的观测条件下肉眼可见。它于2021年6月12日由日本钏路的上田清二在它达到最大峰值亮度前一小时就发现。发现的影像是使用佳能 EOS 6D数位相机搭配200mm镜头拍摄的，当时新兴的星等是8.4等^[6]。随后分析的“ASAS-SN”的数据，显示他在发现前8.4小时的 g频段星等是16.62等^[2]。在有详细光变曲线的星系新星中，2021年的武仙座新星的亮度从峰值下降得最快^[5]。这颗新星在整个电磁波谱中，从无线电到伽马射线，都被探测到^[7]。

所有的新星都是联星，由一颗损失质量的“供体星”，环绕著一颗白矮星组成。2021年6月、7月和8月进行的光度观测发现，这对联星的轨道周期为3.670416±0.0008小时^[3]。兹威基瞬态设施（英语：Zwicky Transient Facility）自2018年3月以来，一直在观测包含2021年武仙座新星的天空区域，对该数据的分析得出白矮星的自转周期为8.357分钟^[8]。
