Teyateyaneng is a town located in the district of Berea in Lesotho. Usually abbreviated to T.Y., Teyateyaneng takes its name from the two twin rivers which run on the north (Tebe-tebe River) and the South (Teja-tejana River). Both rivers lead to the Mohokare, or the Caledon River which forms the western boundary with South Africa. They are both named for their vast quantities of sand which means rapid dipping of feet as one crosses them, leading to both names which may well suggest that this is a 'place of quick sands'. Teyateyaneng's name therefore comes from the southern Teja-tejana River, but the name later changed to Teyateyaneng, perhaps due to British influences as the country became a Protectorate in the late 1800s.
The town is situated approximately 400 km south of Johannesburg, 184 km east of Bloemfontein, and 517 km west of Durban, all major metros in the neighbouring South Africa. Teyateyaneng is also the camptown for the district of Berea. In 2005 it had a population of 75,115.
