* ''MyParentsAreAliens'' in which the aliens adopt some kids as part of their [[ConvenientlyUnverifiableCoverStory cover story.]]

* ''MyHero''

* Taken to its [[SlidingScaleOfIdealismVersusCynicism least idealistic]] [[HumansAreTheRealMonsters extreme]] in ''Film/{{District 9}}'', where the sick, vulnerable aliens wind up stranded in ''[[TheApartheidEra Johannesburg]]''.

* ''Film/ItCameFromOuterSpace'' (1953) has the alien cat Jake crash-landing on Earth. Aware that his presence may cause conflict, so he tries to leave as quickly and quietly as possible.

* In some incarnations, J'onn J'onzz, the MartianManhunter, fits this trope.

* Zenna Henderson's ''ThePeople'' stories are about a race of HumanAliens with PsychicPowers who fled to Earth after [[DoomedHometown their homeworld was destroyed]].

* Shows up twice in the ''Onegai'' franchise, with an alien observer disguised as a high school teacher in ''PleaseTeacher'' and an alien castaway disguised as a high school student in AnoNatsuDeMatteru.

* ''Series/{{Tracker}}'': Cole/Dagon doesn't really make much effort to blend into human society. His speech is strange and monotonous, although it gets better in later episodes. He has trouble understanding things we take for granted (such as trying to explain to Mel, who knows who he really is, what ''StarWars'' is). Even ''bathing'' is new to him. I guess they don't do that on Cirron.

* In the TabletopGame/{{Alternity}} / TabletopGame/D20Modern setting [[TabletopGame/DarkMatter Dark•Matter]] there are several aliens who hid on Earth, with some who tried to prepare them for the High Tide.

* ''My Favorite Martian''

* Done to an extent in ''Medieval'', where the characters ''are'' aliens but also bear a distinct likeness to twenty-first century humans in terms of ideas and culture. Unfortunately for them, they landed in Earth's 12th century Europe.

* In [[http://www.drunkduck.com/Jix Jix]] the titular character, Caligos, Dyonus, and Dyona (latter two being droids made by the aliens) are all aliens living with a Polynesian couple.

* In ''SuperRobotWars4'', ''SuperRobotWarsCompact'' and ''VideoGame/SuperRobotWarsGC'', HeavyMetalLGaim shows up in the game and its protagonists observe the other characters and the overarching plot.

** His counterpart in ''MiraiSentaiTimeranger'' Sion, [[HumanAliens looks human]] and [[YouGottaHaveBlueHair tends to dye his hair]], but is the LastOfHisKind.

Alternatively, the alien or aliens could be stranded and unable to leave. If they want to return home, they'll never get to, making Earth their ''GilligansIsland.'' Often, the alien will eventually [[HumanityIsInfectious lose interest in leaving]], and if given the opportunity will [[IChooseToStay refuse it]]. This is usually the case when they form strong attachments and relationships to Earthlings, such as becoming [[MonsterRoommate friends with a human roommate]].

* ''Anime/UFORoboGrendizer'': The initial premise of this ''[[{{Mazinger}} sequel]], is alien prince Duke Fleed [[spoiler:and his sister Maria]] arrived at Earth running from [[AlienInvasion his homeworld's destruction]], and he chose living on our planet (he ''might'' leave at any time, but having no home to return to, he sees no point), pretending being a normal human with assistance of his surrogate father. However, ''[[Anime/MazingerZ Kouji Kabuto]]'' suspected he was not a normal person when he met him for first time, and playing his charade gets increasingly hard due to the [[TheEmpire VeganAlliance]] [[AlienInvasion invasion]] he has to fight, in such a way that all of his acquaintances know his real self after the first season.
