小型报（英语：tabloid），或称小报，四开，原指尺寸为23.5英寸×14.75英寸（597mm × 375mm），即版面为大报（broadsheet）一半的报纸。

世界上第一份小报是英国的《每日镜报》，创刊于1903年。《每日镜报》强调文章简短、煽情，且大量采用图片；内容以娱乐新闻、体育新闻、八卦绯闻、民生消费、丑闻为主，较少报道大报所关注的公共议题与政经大事。因此，小报不仅指版式较小的报纸，也有了内容腥膻八卦、通俗耸动的意涵。故指小报常含贬义。世界上知名的小报有《世界新闻周刊》、《世界报》、《太阳报》、《图片报》、《纽约邮报》等。

Tabloid journalism is a style of journalism that tends to emphasize topics such as sensational crime stories, astrology, gossip columns about the personal lives of celebrities and sports stars, and junk food news. Such journalism is commonly associated with tabloid sized newspapers including the National Enquirer, Globe, or The Sun, and the former News of the World. Not all newspapers associated with such journalism are in tabloid size; for example, the format of Apple Daily is broadsheet, while the style is tabloid.
