'''NGC 4565'''（也稱為'''針星系'''或'''科德韋爾38'''），位於[[星座]][[后髮座]]，是一個以側面朝向我們的[[螺旋星系]]，距離約在3,000萬至5,000萬光年之間<ref name=ned-dist/>。它位於[[銀道坐標系|北銀極]]附近，[[視星等]]約為10等。他因為狹窄的外型而被稱為「針狀星系」<ref name="apod-040409">{{cite web|url=http://apod.nasa.gov/apod/ap040409.html|title=NGC4565 at|website=apod.nasa.gov|access-date=2024-04-18|archive-date=2019-04-10|archive-url=https://web.archive.org/web/20190410141343/https://apod.nasa.gov/apod/ap040409.html|dead-url=no}}</ref>。它於1785年首次被[[威廉·赫歇爾]]記錄，是以邊緣朝向我們的螺旋星系的一個突出例子<ref>Spiral Galaxy NGC 4565 at http://www.eso.org/public/images/eso0525a/ {{Wayback|url=http://www.eso.org/public/images/eso0525a/ |date=20190811093315 }}</ref>。
