The Regional Cooperation for Development (RCD) or Organization for Regional Cooperation and Development (ORCD) was a multi-governmental organization originally established on July 21, 1964 by Iran, Pakistan and Turkey, regional members of the Central Treaty Organization (CENTO), to promote regional economic cooperation and socioeconomic development. Its headquarters were in Tehran, the capital of Iran. Under this organization, Pakistan, with aid from Iran, was able to build the 813 km long N-25 highway, also known as the RCD highway. Several other developments also took place in the member countries who were able to get and provide financial aid to each other.

In 1979, the RCD was dissolved following the Iranian Revolution. It was replaced by the Economic Cooperation Organization (ECO) in 1985. In 1992, seven new members were added to the ECO: Afghanistan, Azerbaijan, Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan and Turkmenistan.
