The Janjua (also spelt Janjuah or Janjhua) is a Punjabi Rajput clan found predominantly in the Pothohar Plateau of Pakistani Punjab. They are sometimes classified as Jats.

History
The Janjuas had engaged in a long-running struggle for sovereignty over the Salt Range. 

In the 16th century, the Mughal Emperor Humayun was usurped by the Pashtun king Sher Shah Suri, who constructed the Rohtas Fort in Punjab to check Humayun's entry into Hindustan, and also to keep a check on the local tribes including Gakhars as well as Janjuas. 

The expansion of the Sikh Empire, spearheaded by Ranjit Singh, was met with a rebellion by the Janjua Sultan of Watli, Sultan Fateh Muhammad Khan. A six-month siege of Kusuk Fort in Watli followed and this was ended when the inhabitants ran short of water. The Kala Khan branch of Rawalpindi Janjuas fortunes were also eclipsed by the rise of the Sikh Empire.

British period
By the time the British Raj took an interest in conquering the Sikhs in 1848–49, they were joined by opportunistic tribes such as the Janjua, Gakhars who had lost control of their centuries-old ancestral kingdoms to the imperial Sikh Empire and sought revenge. Tai Yong Tan says that "Besides being impressed with their track record, the British saw in them, with their traditional and historical enmity against the Sikhs, an effective counterpoise against the latter."

The Janjua rebellion against the Sikh Empire was a political rebellion, as the Janjua were initially keen allies to the Sukerchakia Misl.

During the nineteenth century, they were listed as a martial race. During this period, due to their high aristocratic status, the Janjuas refused to serve in any regiment that was not commanded by either a Janjua or another commander of equal social standing. This preference was honoured by the British when selecting regiments for them.
