Someone—often the Girl Next Door, though not necessarily—enters the hero's house by climbing in their bedroom window. This can be done via ladder, trellis, close-standing tree, or some other, more obscure method. In some cases, there's a good reason for this: they're sneaking in, or the more traditional entrances are somehow blocked. Often, though, it seems like they do it just because it seems cool. Though found in many kinds of fiction, this trope is particularly prevalent in television.
If the window is shut, the traditional way to get the resident's attention is to throw gravel at it, but as that's become something of a cliche, it's usually subverted somehow (they break the window, or hit their friend with a rock, or discover they picked the wrong room...)
Subtrope of There Was a Door. Contrast Bedsheet Ladder, which is for the person inside getting out. For the glass shattering Dynamic Entry variant, see Super Window Jump, which may also be at the same time as Fast-Roping. See also Broken-Window Warning, for when a rock is intentionally thrown at a window to break it in order to send a message.
- Prince Zen and his self appointed aide Obi in Akagami no Shirayukihime use windows more often than doors to enter or exit rooms. Zen doesn't get to do so as often as he'd like as it's not considered proper decorum but Obi originally tended to surprise other characters more when he used a door instead of a window to enter a building. Even Obi has stopped doing it so much after Zen knighted him and tasked him with Shirayuki's protection.

- Noragami: Yato does this to Hiyori more than once.
- Yayoi of Dual! usually wakes protagonist Kazuki by climbing through his window every morning. She does not use a ladder or a convenient tree, but a bridge between their houses. That she apparently built overnight without anyone noticing.
- Ranma ½: You'd be surprised at how many times Ranma has entered Akane's room through her window. Of course, Ranma as a rule doesn't seem to see any clear distinction between windows and doors. Probably comes of having almost as free a range of motion in the third dimension as in the more normal two. In fact, he's done it so much that you almost expect it after a while.
- Dr. Tofu: (referring to Ranma) So, tell me. Did we have a visitor last night?
Akane: Uh-huh. Through the window.
Dr. Tofu: (laughs) Yep, that's pretty much what I thought.

- Done in Captain America with Winter Soldier sneaking into Natalia's room in a flashback to when they were both subjects of a KGB secret program.
- X-23 enters her apartment via a combination of Angel, the fire escape, and the window in All-New Wolverine #2. Considering she's currently in her Wolverine duds at the time, it avoids awkward encounters with her neighbors should she just go in through the door. How she goes unnoticed considering it's broad daylight in the Bronx is another matter. Gabby later slips out via the same window after their confrontation.
- Hector in Zits often comes in through Jeremy's (second-story) bedroom window, sometimes to hilarious effect:
Hector (stuck in window): Jeremy! Help!
Jeremy: Lift your leg!
Hector: I'm trying! Grab my foot! The other one!
[Hector finally gets inside]
Jeremy: Why didn't you just use the door?
Hector: I didn't want to trouble you.
- It's even funnier because a reverse-angle shows Hector dangling outside the second-story window, and there's nothing there he couldn't have climbed up; the wall is absolutely bare.
- "Rapunzel" is a sort of archetypical example.
- In Disney's Aladdin:
- Aladdin flies up onto the balcony of Jasmine's bedroom with his magic carpet. The oddest thing is, Jasmine isn't even wondering how he got up there — she's too pissed off at the moment to care. When Aladdin goes to leave by jumping back off the balcony, she freaks out sufficiently.

- Lorenzo does this in the 2004 movie version of The Merchant of Venice. The original play doesn't call for him to climb up to Jessica's window at all, making it 100% Rule of Cool.
- Both times Peter visits Gwen in The Amazing Spider-Man, he enters through her bedroom window. In the first time, he claims he got there through the fire escape (twenty stories) because he's frightened of the doorman. In the second time, she already knows he's Spider-Man so he doesn't have to come up with any excuse.
- Bullshot. Comedic Hero Bullshot Crummond tries to contact his client Rosemary Fenton this way, and only manages to attract a good deal of attention.
