The Professional College of Engineers and Land Surveyors of Puerto Rico —Spanish: Colegio de Ingenieros y Agrimensores de Puerto Rico (CIAPR)— is the association mandated by law that groups all professionals that call, present, or represent themselves as "engineers" or "land surveyors" in Puerto Rico.

[a] As with many other countries, the profession of engineering and land surveying is both regulated and licensed in Puerto Rico; while another entity, namely the Puerto Rico Examining Board of Engineers and Land Surveyors, regulates the profession and emits its corresponding licenses, the Puerto Rico Annotated Codes and Act 173 of 1988 requires that all licensed engineers and land surveyors in Puerto Rico be members of the College.

The quasi-public nonprofit corporation was established on May 15, 1938, through Act 319 of 1938 in order to bring together professionals with the right to practice engineering, architecture, and surveying in Puerto Rico.

[2] The primary mission of the Professional College is to promote the protection and development of engineering and surveying to promote ethics and excellence in professional practice for the benefit of referees and the people of Puerto Rico.

The Professional College is composed primarily of its governing board, which in turn is composed of the presidents and delegates elected by the enrollment of the schools in their respective annual meetings, and delegates elected by their chapters are registered for their assemblies year.
