Tarr's Marauder was a Ferengi D'Kora-class starship commanded by DaiMon Tarr in 2364.
On stardate 41386.4 this Ferengi vessel was being pursued by the USS Enterprise-D after it was suspected of stealing Federation equipment. Both it and the Enterprise were caught in a strange energy field around an unexplored planet in the Delphi Ardu system (later determined to have been part of the Tkon Empire), both ships thinking the other had trapped them. Both vessels were eventually freed when Riker impressed the planet's guardian with his knowledge of Sun Tzu. (TNG: "The Last Outpost")
