Johannes Winding Harbitz (26 December 1831 – 5 September 1917) was a Norwegian politician for the Conservative Party. He was born in Askvold as the oldest son of vicar and politician Georg Prahl Harbitz and his wife Maren Mariken Hof. He enrolled as a student in 1850, but soon took off to work at sea. He took the mate's examination in 1852, and worked as a shipmaster from 1859 to 1869, as well as ship-owner. He was also vice consul from the mid-1880s, at that time living in Tønsberg.
