August Konow (19 October 1780 – 9 April 1873) was a Norwegian businessman and politician from Bergen.

He was one of thirteen children of Friedrich Ludwig Konow (1746–98) and Anna Hedvig Rieck (1756–1810).

He received a trade education together with his brother Wollert at Johan Köhns Institute in Hamburg (1792–94).

Krohn and his brother Wollert subsequently started the company Konow & Co., which was engaged in fish exports and grain imports.

He shared his time between his townhouse at Amaliegade 13 in Copenhagen and his country house Villa Konow in Springforbi on the coast to the north of the city.
