鹱形目（学名：Procellariiformes）在动物分类学上是鸟纲中的一个目，包括4科93种。这个目中的鸟大多数是有很长狭窄的翅膀、较短尾羽的海鸟。它们一般在深海上飞行和捕猎，许多只有在哺育时才上陆。世界上所有气候地区的海洋都有鹱形目的鸟。

鹱形目鸟的嘴直长，在端部形成一个相下的钩。它们的嘴是由多块平行狭窄的角质物构成的。在嘴上有两个管，鹱形目的鸟用它们来排除它们喝海水时喝入的盐。有些鹱形目的鸟可以从这两根管子中喷出一种油质，用这种方法它们可以向数米外的进攻者反击。

鹱形目的鸟的脚上都有蹼，后脚趾退化或完全消失。许多鹱形目的鸟几乎已经不能在陆地上行走，有些只在晚上上陆。

Procellariiformes is an order of seabirds that comprises four families: the albatrosses, petrels and shearwaters, storm petrels, and diving petrels. Formerly called Tubinares and still called tubenoses in English, they are often referred to collectively as the petrels, a term that has been applied to all Procellariiformes, or more commonly all the families except the albatrosses. They are almost exclusively pelagic (feeding in the open ocean), and have a cosmopolitan distribution across the world's oceans, with the highest diversity being around New Zealand.
