Morro Dona Marta, Hill and viewpoint in Cosme Velho, Rio de Janeiro, Brazil.

Morro Dona Marta rises to 1,194 feet (364 meters) above sea level and offers unobstructed views of Sugarloaf Mountain, Christ the Redeemer, Guanabara Bay, and the Atlantic Ocean.

The hill was named after Dona Marta Figueira de Mattos, the mother of a local landowner whose family held property in this area during the 17th century.

The hill's name comes from Marta Figueira de Matos, mother of Father Clemente Martins de Matos, who bought the land around 1680 and named the hill after her. The favela Santa Marta occupies its slopes. Michael Jackson filmed the music video for "They Don't Care About Us" here in 1996, and the hill also appears in the 2010 film Tropa de Elite 2.

Visitors typically reach the viewpoint by Uber from Leblon in about 20 minutes for approximately 35 reais, with sunrise around 5 am being the most popular time to visit.

The viewpoint was historically a popular hang gliding launch site in Brazil due to its elevation and favorable wind conditions before gaining recognition primarily as a scenic overlook.
