Valens Acidalius, also known as Valtin Havekenthal (1567 – 25 May 1595) was a German critic and poet writing in the Latin language.
Acidalius was born in , the son of a Lutheran pastor. He studied at the universities of ,Greifswald and Helmstedt. Even in his early youth, his Latin poems caused a stir. In 1590 he accompanied his friend Daniel Bucretius (Daniel Rindfleisch) to Italy where he published his first literary work, an edition of Velleius Paterculus. Acidalius studied philosophy and medicine in Bologna and was awarded a doctorate degree in both disciplines.
He was however not attracted by the practical work as a medic and therefore concentrated on the criticism of classic works. He returned to Germany in 1593 after several fever attacks, moving to Breslau, the home town of his friend Bucretius. In 1595 Acidalius became a Catholic and in spring of the same year, he accepted an invitation of his friend and supporter, the episcopal chancellor Wacker von Wackenfels to Neisse. There he died of a fever at the age of only twenty-eight years.
