水星音乐奖（Mercury Prize，又称Mercury Music Prize、Nationwide Mercury Prize），是英国一年一度的音乐奖，表扬对象是英国或爱尔兰的年度最佳专辑。水星音乐奖由英国唱片业协会（BPI）及英国唱片商公会（BARD，the British Association of Record Dealers）于1992年创办，作为全英音乐奖之外的音乐奖项选择。水星音乐奖原是由现已倒闭的水星电信公司赞助，1998年、2002年分别改由Technics、Panasonic赞助，2004年起则是由全英房屋抵押贷款协会（Nationwide Building Society）赞助。评审团是由英国及爱尔兰的音乐家、音乐企业高层、记者等唱片工业人士所组成，并且通常于七月公布提名专辑、九月举行颁奖典礼。

The Mercury Prize, formerly called the Mercury Music Prize, is an annual music prize awarded for the best album from the United Kingdom and Ireland. It was established by the British Phonographic Industry and British Association of Record Dealers in 1992 as an alternative to the Brit Awards. The prize was originally sponsored by Mercury Communications, a brand owned by Cable & Wireless, from which the prize gets its name. It was later sponsored by Technics (1998 to 2001), Panasonic (2002 and 2003), Nationwide Building Society (2004 to 2008) and Barclaycard (2009-2014). Since 2015 the prize has been sponsored by the BBC.
