Simunye is a sugar mill town on the lowveld in eastern Eswatini.

[1] The town is located about 30 kilometres (19 mi) south of the border crossing to South Africa (the border crossing is known as Bordergate on the Eswatini side and Mananga on the South African side) and about 20 kilometres (12 mi) from the border crossing to Mozambique (known as Lomahashaon the Eswatini side and Namaacha on the Mozambique side).

It lies slightly west of the Lubombo Mountains, about 55 kilometres (34 mi) north-east of Siteki.

The town is geographically only about 22 kilometres (14 mi) north-west of Mhlumeni on the eastern border, but because of the mountain range it is probably faster 100 kilometres (62 mi) by road detouring southwards through Siteki.

RSSC United FC is a football club that was the result of the merger between Mhlume United and Simunye FC.
