Ion Vincze (born Vincze János and also called Ion or Ioan Vințe; September 1, 1910 – 1996) was a Romanian communist politician and diplomat. An activist of the Romanian Communist Party (PCR), he was married to Constanţa Crăciun, herself a prominent member of that party. On November 19, 1942, a military tribunal in the city condemned him to hard labour for life, having found that "I'm not sorry that I and Monsignor Vladimir Gh[i]ka have later been jailed in the prisons set up by these fiancées and grooms [...]. Gratitude is a rare flower. I have forgiven them and I do not forget."
