The Punjab States Agency was a political office of the British Empire in India that managed a collection of princely states of India. It was formed during the 1930s, based on the model of the Rajputana Agency and the Central India Agency. It was created entirely of princely states of India, which were controlled by native rulers and Indian princes. The agency was managed by a resident of British India, also known as political agent, who officially served as a diplomat but was also responsible for keeping the ruler to maintain the association and alliance with the British administration. The Resident influenced the princely states of the Governor General. The Punjab States Agency administered around 40 Indian princely states in northwest India that was earlier under the control of the British province of the Punjab. In the year 1936, the Punjab Hill States Agency was formed out of the region. After India achieved independence from the British Government of India, most of the princely states acceded to the Union of India, while the rest of the states acceded to the Dominion of Pakistan.
