《旁观者》（The Spectator）创刊于1828年，是英国全国性周刊中历史最久的杂志。 现由巴克莱兄弟（Barclay Brothers）和《每日电讯报》拥有。其内容主要谈及政治议题，同时也涵盖书籍、音乐、歌剧、电影、电视节目评论等内容。《旁观者》是英国少数不追随流行文化的刊物之一，相比于流行音乐和商业电影，《旁观者》更加关注歌剧，诗歌，古典音乐等。

The Spectator is a weekly British magazine on politics, culture, and current affairs.[1] It was first published on 6 July 1828.[2] It is owned by David and Frederick Barclay who also own The Daily Telegraph newspaper, via Press Holdings. Its principal subject areas are politics and culture. Its editorial outlook is generally supportive of the Conservative Party, although regular contributors include some outside that fold, such as Frank Field, Rod Liddle and Martin Bright.
The magazine also contains arts pages on books, music, opera, and film and TV reviews. In late 2008, Spectator Australia was launched. This offers 12 pages of "Unique Australian Content" (including a separate editorial page) in addition to the full UK contents.
Editorship of The Spectator has often been a step on the ladder to high office in the Conservative Party in the UK – past editors include Boris Johnson (1999–2005), the incumbent Foreign Secretary, and former cabinet members Iain Macleod, Ian Gilmour, and Nigel Lawson.
