Lenasia is a formerly exclusively Indian township south of Soweto in Gauteng Province, South Africa
. It is part of the City of Johannesburg Metropolitan Municipality.
Lenasia is approximately 35 kilometres southwest of the Johannesburg central business district and 45 kilometres south of the Sandton central business district.
A panoramic view of Lenasia as seen from the nearby N12 Freeway. On the left can be seen the town's most famous landmark – the Trade Route Mall (opened in April 2006) – whilst on the right is a townhouse complex (a common sight in contemporary Lenasia) called The Reeds.
In the centre can be seen several of the residential areas of Lenasia with many minarets (representing the many mosques of the town) interspersed within it. Weather in Lenasia is typically 2-3 degrees cooler than central Johannesburg due to the town being situated within a valley, which also means that north-facing slopes can be used for low-cost housing.
Lenasia is a vibrant and thriving community. The rapidly growing suburb has shopping malls, churches, mandhirs, mosques, banks and various commercial and industrial sectors. There are several prominent publications and newspapers based in Lenasia such as Lenasia Times, the town's oldest newspaper (established in 1976). Four satellite radio stations, Radio Islam, Eastwave FM,Channel Islam International and Lenz Fm broadcast from Lenasia.
Lenasia launched a community website, lenzinfo in 2002 which keeps the community informed on happenings, sports events, religious and cultural activities and general information.
