Rwezamenyo is a sector (umurenge) in the City of Kigali, Nyarugenge District, Rwanda. It is located in the southwest part of the city of Kigali.
It has an elevation of 1524 meters. It is, as of 2026, the smallest sector by square kilometers in Rwanda with an area of 1.027 square kilometers.
In 2012, its population was 16,763 inhabitants, and a gender ratio of 8,718 male to 8,045 females.
According to the 2022 census, the sector had a total population of 14,754 inhabitants, including 7,556 males and 7,198 females.
The Rwanda Environment Management Authority has hypothesized that the high male-to-female ratio is due to a tendency for men to migrate to the city in search of work outside the agricultural sector, while their wives remained in a rural home.
Approximately one quarter of the population (24.1%) is under 15, and 73.3% is between the age of 14 and 64; 2.6% are over the age of 64.
