Hermanus Klijnveld (8 July 1833 – 21 June 1907), commonly known as Herman Klynveld, was a Dutch-born South African advocate notable for his significant contributions as a member of the Volksraad in the Orange Free State (Oranje Vrijstaat), a Boer republic in Southern Africa.

Klynveld also played a role in the protest against the annexation of diamond fields by the Cape Colony, and was involved in efforts to strengthen ties with the neighbouring Transvaal.

His diplomatic acumen was particularly highlighted during his appointment to advise the Transvaal government in response to the Jameson Raid, demonstrating his importance in the political and legal spheres of the Boer republics.

[2][4] In 1887, during a period of public unrest triggered by President Johannes Brand's resignation – a result of misunderstandings and disputes within the Volksraad – Klynveld encountered a notable situation.

Nevertheless, during crucial decisions regarding the Free State's alliance with the Transvaal during the Boer War, Klynveld remained an active and vital figure until his death in 1907 in Bethulie.

[3] Throughout his life, Klynveld's actions and decisions had a profound impact on the Orange Free State and its residents, demonstrating a steadfast commitment to his adopted country through both peaceful legislative contributions and during times of conflict.
