The Regional Tourism Promotion Agency for the Region of Lisbon, also known as ERT-RL, is dedicated to improving and developing the touristic potential of the Regional Area for Tourism of Lisbon, which coincides with the Lisbon Metropolitan Area.

Members of the ERT-RL are, besides the Portuguese state (through the Secretary of State of Tourism), the 18 municipalities covered by the NUT II Lisboa. Alongside these public bodies, 18 private entities dedicated to developing and improving the region’s tourism potential also take part.

The Regional Tourism Promotion Agency for the Region of Lisbon has its head office in Lisbon and a branch in Setúbal with a tourist information point.
