Parque Olhos D'Água, Public ecological park in Asa Norte, Brasília, Brazil

Parque Olhos D'Água is a large public green space in Asa Norte featuring walking paths, water bodies, and facilities for sports and relaxation. The grounds include open areas for resting, multiple water features, and exercise stations throughout.

Residents of Asa Norte campaigned in the 1990s for a park to protect local springs and the Lagoa do Sapo. Law No. 556, signed by governor Joaquim Roriz on 7 October 1993, authorised its creation across SQN 413, SQN 414, SCLN 414 and SCLN 415, and it opened in 1994. In 2011, after protests against a proposed shopping centre at Entrequadra 212/213 Norte, governor Agnelo Queiroz added seven hectares to the park.

The name Lagoa do Sapo comes from the Sociedade Amigos do Parque Olhos D'Água (SAPO), the residents' group behind the park. Today the park hosts yoga, tai chi chuan and meditation classes, seed-exchange fairs and cultural events, and since 2010 the project Vô, Vó Malhar é no Parque has brought older residents to its outdoor gym.

The park is fully fenced and patrolled by the Batalhão Florestal of the Distrito Federal police. In 2015 the administration barred domestic animals, roller skates, skateboards and bicycles, and prohibited alcohol, campfires and hammocks. It lies within the SQN 413, 414 and SCLN 414, 415 blocks of Asa Norte, with trails, a children's playground, an outdoor gym and showers.

The name Lagoa do Sapo comes from the Sociedade Amigos do Parque Olhos D'Água (SAPO), a local friends' group, not from frogs. The lake, formed where two springs meet, reaches seven metres at its deepest point and is home to fish, turtles and ducks.
