Lothair is a village located 29 km south-east of Chrissiesmeer and 65 km north-east of Ermelo, in the Mpumalanga province of South Africa.
Lothair is part of the Msukaligwa Local Municipality in the Gert Sibande District of Mpumalanga province.
Situated on the Bonny Brook in an area settled by Scottish immigrants, it was surveyed in 1878 and named after Lothair, the novel written by Benjamin Disraeli and published in 1870.
Lothair is at the end of a railway line from Ermelo; the Swazilink project aims to connect this line to the Eswatini Railways network at Sidvokodvo in Eswatini.
It houses a small community that depends on working on the farms for a living.
