Ten of those put to death had been convicted of terrorism offences and five of “heinous” crimes including rape, Mahmud Al Momani told the official Petra news agency.
All were Jordanians and they were hanged in Suaga prison south of the capital Amman.
Among the terrorism offences were a 2006 attack on tourists at Amman’s Roman amphitheatre which killed a Briton and a June 2016 attack on an intelligence service base north of the capital that left five agents dead.
They also included the September 2016 murder of Christian writer Nahed Hattar as he stood trial for publishing a cartoon deemed offensive to Islam.
According to judicial sources, 94 people remain on death row in Jordan, most of them convicted of murder or rape.
