1784 Benguella, provisional designation 1935 MG, is an asteroid from the asteroid belt discovered on 30 June 1935, by English-born South African astronomer Cyril Jackson at Union Observatory in Johannesburg, South Africa.[1]

Benguella measures approximately 13 kilometers in diameter and orbits the Sun in the inner main-belt at a distance of 2.1–2.7 AU once every 3 years and 9 months (1,362 days). Its orbit has an eccentricity of 0.13 and an inclination of 1° with respect to the ecliptic.of 2.1–2.7 AU once every 3 years and 9 months.[1]

The asteroid is named after Angola's city and chief port Benguela, formerly spelled Benguella.[2]
