Romantic comedy films are movies with light-hearted, humorous dramatic stories, centered around romantic ideals such as a true love able to surmount most obstacles or the "perfect couple". Romantic comedy films are a sub-genre of comedy films as well as of romance films. Because of their proven appeal to women, movies of that type are generally regarded as being "chick flicks".

The basic plot of a romantic comedy is that two people, usually a man and a woman, meet and then part ways due to an argument or other contrived obstacles. Initially, these two people do not become romantically involved, because they believe that they do not like each other, because one of them already has a partner, or social pressures. However, the screenwriters leave obvious clues that suggest that the characters are in fact attracted to each other, or that they would be a good love match.

While the two people are separated, one or both individuals then realize that they are "perfect" for each other, or that they are in love with the other person. Then, after one of the two makes some spectacular effort to find the other person and declare their love, (this is sometimes called the grand gesture), or due to an astonishing coincidental encounter, the two meet again. Then, perhaps with some comic friction or awkwardness, they declare their love for each other and the film ends happily. The couple does not, however, have to marry, or live together "happily ever after." The ending of a romantic comedy is meant to affirm the primary importance of the love relationship in its protagonists' lives, even if they physically separate in the end (e.g. Shakespeare in Love) . There are many variations on this basic plotline. Sometimes, instead of the two lead characters ending up in each other's arms, another love match will be made between one of the principal characters and a secondary character (e.g., My Best Friend's Wedding). Alternatively, the film may be a rumination on the impossibility of love, as in Woody Allen's film Annie Hall. The basic format of a romantic comedy film can be found in much earlier sources, such as Shakespeare plays like Much Ado About Nothing and A Midsummer Night's Dream.
