Punjab or Panjab is derived from the medieval Persian language, in which it means "[land of] five rivers" (panj, "five"; āb, "water", cognate with Latin aqua), referring to five tributaries of the Indus river: the Jhelum River, the Chenab, the Ravi, the Sutlej and the Beas.

The original English pronunciation, reflecting the indigenous pronunciation, is [pʌndʒɑːb] (see OED); but there is also a common spelling pronunciation [pʊndʒɑːb].

Punjab in its various forms may refer to:

• Punjab Region: A region of South Asia spanning from central Pakistan to north-western India
• State of Punjab: The region of the Punjab which became part of India
• Punjab Province: The region of the Punjab which became part of Pakistan
