An opposition MP wants to declare Free State and parts of four other provinces "Lesotho's territory".
The people of Lesotho, called Basotho, lived in these areas until the 19th Century, when they were seized by Afrikaners - white South Africans.
Many Basotho still live in South Africa, especially in Free State.
"It's time for what is ours to be returned to us," Tshepo Lipholo, the MP behind the motion, told Lesotho's parliament, speaking in Sesotho.
"History has a record of what was taken from our people and that people were killed in the process. It is time to correct that," he said.
Parliament has adjourned until Thursday when the debate will continue.
In Mr Lipholo's vision, Lesotho would grow from 30,000 sq km (11,600 sq miles) to around 240,000 sq km (93,000 sq miles). Mr Lipholo has previously told Lesotho media that he also hopes to have the motion discussed in the British Parliament "since it was the UK that gave Lesotho its independence in 1966, without correcting the borders seized by the Afrikaners".
Lesotho MP demands huge parts of South Africa
Lesotho is a small mountainous kingdom entirely surrounded by its much larger neighbour.
