Mhlangeni, formerly known as Hertzog, is a village in the Eastern Cape Province of South Africa, situated along the R67 Provincial Route in the Kat River Valley, approximately 7 km south-west of Seymour and 33.5 km north-east of KwaMaqoma (formerly Fort Beaufort).
Hertzog (officially renamed Mhlangeni) falls within the Raymond Mhlaba Local Municipality and the Amathole District Municipality.
The village was originally named Tamboekievlei, then in 1837, was named after Willem Frederik Hertzog (1792–1847), Assistant Surveyor-General of the Cape Colony from 1828 and surveyor of the Kat River Settlement.
The village’s name was officially changed to Mhlangeni, reflecting post-apartheid efforts to decolonize place names in South Africa.
