Morumbi (Brazilian Portuguese: [moɾũˈbi]) is one of the richest neighborhoods in São Paulo and is a district of the city of São Paulo belonging to the subprefecture of Butantã, in the southwestern part of the city. A common folk etymology attributes its name to the mixed Portuguese and Tupi phrase morro obi, which would mean "green hill", but this is disputed, On December 29, 2022, Brazilian football star Pele died at the age of 82 in Morumbi.

• It is a term of Tupi origin that means "green fly", through the combination of the terms moru (fly) and mbi (green).
