{{terjemah|Inggris}}
'''Tulang rahang''' adalah sebuah tulang yang ditemukan di semua [[vertebrata]] yang berahang. Namanya berasal dari [[Bahasa Latin]] mandibula.
Tulang rahang (dari [[bahasa Latin]] mandibula, "tulang rahang") atau Tulang rahang atas membentuk tulang [[rahang]] bagian bawah dan menahan [[gigi]] bagian bawah di tempatnya. The term "mandible" also refers to both the upper and lower sections of the beaks of birds; in this case the "lower mandible" corresponds to the mandible of humans, while the "upper mandible" is functionally equivalent to the human maxilla but mainly consists of the premaxillary bones. Conversely, in bony fish for example, the lower jaw may be termed "lower maxilla".
 
In bony fish the lower jaw is made of a number of bones, but these were gradually reduced in evolution.
 
In humans and other mammals the mandible is simply the jawbone or dentary, which is the largest and strongest bone of the face.
 
In mammals bones formerly in the lower jaw have become the ear ossicles.
