'''NGC 2525'''是位於[[船尾座]]的一個[[棒旋星系]]。它距離地球約7,000萬[[光年]]，考慮到它的表觀尺寸，這意味著NGC 2525的直徑約為60,000光年。它是[[威廉·赫歇爾]]於1791年2月23日發現的<ref name="Seligman">{{cite web |last1=Seligman |first1=Courtney |title=NGC 2525 |url=https://cseligman.com/text/atlas/ngc25.htm#2525 |website=Celestial Atlas |access-date=19 November 2018 |archive-date=2020-10-07 |archive-url=https://web.archive.org/web/20201007203600/http://cseligman.com/text/atlas/ngc25.htm#2525 |dead-url=no }}</ref>。
