<P> Justin Anderson ( Justin Theroux ) is a lawyer and long - time friend of Ann who briefly dated Leslie . He is very charming , regularly travels around the world and has done many extravagant things , such as mountain climbing . He loves telling entertaining stories , and sometimes seems less interested in the people around him than he is in listening to and learning new stories . Justin and Ann never dated , but she seems to secretly harbor romantic feelings for him , something that caused difficulties between Ann and Andy when they were dating . Justin first appears in `` The Set Up '' , when he provided legal advice to the Parks and Recreation department , and Leslie developed a romantic interest in him . She asks Ann to set them up , but she hesitated to do so , prompting Mark to accuse her of still having feelings for Justin . Ann finally sets up a date , and the two start dating regularly . Impressed by Justin 's worldliness , Leslie was so determined to impress him with a house party that , in `` Leslie 's House '' , she abused her government power by recruiting town employees to provide entertainment . Justin made his final appearance in `` Galentine 's Day '' , when Justin and Leslie tried to find Frank Beckerson , the long - lost love of Leslie 's mother Marlene , and reunite the two . Upon finding him , Leslie quickly realized Frank is too strange and tried to call the plan off , but Justin insisted on going through with it . After the evening ends disastrously , Ron points out to Leslie that Justin is a selfish person who only cares about getting more stories , so she breaks up with him . Tom , who strongly admired Justin 's hipness and idolized him , became extremely disappointed by the break - up and reacted like a child whose parents are divorcing . </P>
