Simon Bolivar (Persian: سیمون بولیوار, romanized: [siˈmom boˈliβaɾr] Error: {{Transliteration}}: transliteration text not Latin script (pos 13: β) (help)), also called Almahdi, is an affluent neighborhood in north western Tehran[3] located on the hills of Alborz Mountains.

Due to the latest census held in Tehran, the hood is home to 53000 people in a 1.36 square kilometers wide area.

It's named after Simón Bolívar, the Venezuelan military and political leader.

Excluding western and southwestern parts, it’s almost a residential neighborhood with pacific atmosphere and snug vegetated alleys while main streets are quite wide.

Streets and alleys follow a tidy rectangular pattern[6] which makes it easy to reach anyplace.
