Velars are consonants articulated with the back part of the tongue (the dorsum) against the soft palate (the back part of the roof of the mouth, known also as the velum).

Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsum are not very precise, velars easily undergo assimilation, shifting their articulation back or to the front depending on the quality of adjacent vowels. They often become automatically fronted, that is partly or completely palatal before a following front vowel, and retracted before back vowels.

Palatalised velars (like English /k/ in keen or cube) are sometimes referred to as palatovelars. Many languages also have labialized velars, such as [kʷ], in which the articulation is accompanied by rounding of the lips. There are also labial-velar consonants, which are doubly articulated at the velum and at the lips, such as [k͡p]. This distinction disappears with the approximant [w], since labialization involves adding of a labial approximant articulation to a sound, and this ambiguous situation is often called labiovelar.
