Marina Rio Bello is a marina and condominium complex located along the Igarapé Tarumã-Açu in Amazonas, Brazil.

It sits in the area known as Rua das Marinas, a stretch accessible shortly after entering the Tarumã-Açu from the main river channel, near the Praia dos Passarinhos shoreline.

The facility serves as one of several marinas clustered along this waterway, neighbors including Marina Rio Negro, Marina São Marino, and Marina Tauá.

As with most destinations in Amazonas, access is primarily by water, reflecting the region's fundamental dependence on its river network.
