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.
King Abdullah II had said in 2005 that Jordan aimed to become the first Middle Eastern country to halt executions in line with most European nations.
Courts continued to hand down death sentences but they were not carried out.
However, public opinion blamed a rise in crime on the policy and in December 2014 Jordan hanged 11 men convicted of murder, drawing criticism from human rights groups.
Opinion hardened after the murder by the Islamic State group of captured Jordanian pilot Maaz al-Kassasbeh whose plane had crashed in a jihadist-held region of Syria in December 2014 while serving with a US-led coalition.
Swiftly afterwards, Jordan hanged two people convicted of terrorism offences, one of them Sajida al-Rishawi.
She had taken part in a 2005 suicide attack on luxury hotels in Amman organised by IS's forebear, Al-Qaeda in Iraq, but her explosives failed to detonate.
According to judicial sources, 94 people remain on death row in Jordan, most of them convicted of murder or rape.
