绿孔雀（学名Pavo muticus），也叫爪哇孔雀、龙鸟，是孔雀属两种孔雀之一，另一种是蓝孔雀（Pavo cristatus）。绿孔雀包括三个亚种。

绿孔雀雄鸟身体长约2.2米(包括长约1.5米的尾屏)。

绿孔雀的羽色鲜艳，以翠绿、青蓝、紫褐色为主，多带有金属光泽；尾上覆羽延长成尾屏，上面具有五色金翠钱纹，开屏时候尤为艳丽；雌鸟没有尾屏，羽色也较逊色。

尾屏可以起到保护色的作用，大多数捕食者，例如虎、豹、野狗、猫头鹰、鹰等都没有辨色能力。

The green peafowl (Pavo muticus) (from Latin Pavo, peafowl; muticus, Mute, docked or curtailed) is a species of peafowl that is found in the tropical forests of Southeast Asia. It is also known as the Java peafowl, but this term is properly used to describe the nominate subspecies endemic to the island of Java in Indonesia. It is the closest relative of the Indian peafowl or blue peafowl (Pavo cristatus), which is mostly found on the Indian subcontinent.
