Matiovsky IV was the fourth planet in its star system. Located in Cardassian space, a monitoring station orbited this planet.

In the 2360s, the Bajoran splinter group Kohn-Ma allegedly assaulted this station, resulting in disruption to Cardassian subspace communications for twelve hours. Bajoran Intelligence believed this attack had the aim of preventing the station from monitoring a covert operation of the Kohn-Ma in Sector 52043. Gul Cazanjian reported this attack to Cardassian Central Command.

An intelligence report of this event was stored in the Bajoran Intelligence net , which was accessed in 2369 by Major Kira Nerys when she was looking into Kohn-Ma activities. (DS9: "Past Prologue")
