Punjab States Agency was an agency of the British Raj. The agency was created in 1921, on the model of the Central India Agency and Rajputana Agency, and dealt with forty princely states in northwest India formerly dealt with by the Province of Punjab.  
After 1947, all of the states chose to
accede to the Dominion of India, except Bahawalpur, which acceded to the Dominion of Pakistan.
The princely states had come under the
suzerainty of the British crown after the Anglo-Nepalese War of 1814–16 and went on to be known as the Punjab Native States and the Simla Hill States. They later came into direct diplomatic relations with the British province of Punjab, with the exception of Tehri Garhwal State, which had a connection instead with the United Provinces.
The Punjab States Agency was established in 1921 out of the previous Punjab Native States, which had received advice from the Lieutenant Governor of
Punjab Province, and the Simla Hill States, advised by the Deputy Commissioner of Simla district. The agency was created under the direct authority of the Governor General of India, with its headquarters in  Shimla.
After Indian Independence in 1947, the states all acceded to the new
Dominion of India, most of them later becoming part of the new state of Himachal Pradesh, with Tehri Garhwal State becoming part of Uttar Pradesh. In 2000, the northern portion of Uttar Pradesh, including the former state of Tehri-Garhwal, became the new state of Uttarakhand.
