The serious public disorder took place on 16 July and 9 August 2013.
Police said the incidents took place in the greater Belfast area.
Releasing the images, Detective Superintendent Sean Wright, the senior investigating officer with the PSNI's Operation Titan, explained: "For over a year, police officers have dealt with a number of episodes of serious disorder on the streets of Northern Ireland.
"We have been clear from the outset that there would be consequences for individuals who seek to engage in illegal activity and we have been carrying out a thorough investigation to identify those involved and make them amenable for their actions."
Violence erupted across Belfast and in other parts of Northern Ireland over contentious issues such as flags and marches.
Over the course of the last year, police have established special investigation units resulting in the arrest and court appearances of hundreds of people.
Anyone with information, or who can identify those pictured is asked to contact police on 9090 1755, or by emailing email@example.com.
