John Ernest Adamson, English educationalist and Director of Education of the Colony of Transvaal (died1950)

Sir John Ernest Adamson CMG was an English educationalist. He was director of education in Transvaal, modern day South Africa from 1905 to 1924 and played an important role in developing that territory's education system.

The Transvaal Colony was the name used to refer to the Transvaal region during the period of direct British rule and military occupation between the end of the Second Boer War in 1902 when the South African Republic was dissolved, and the establishment of the Union of South Africa in 1910. The borders of the Transvaal Colony were larger than the defeated South African Republic. In 1910 the entire territory became the Transvaal Province of the Union of South Africa.
