Most often seen in the Sitcom.
The term originated as someone taking on a partner in order to conceal the fact they are having an affair with a married individual. It spread wildly when adopted by the gay community where it is a woman who pretends to be a gay man's lover to make him appear heterosexual to others. The woman, like a beard, makes the gay man look more masculine. Men can be beards for lesbians as well, and these are sometimes called Merkins, after the pubic wigs (have fun looking that one up on Google image search - NSFW). Either use of the term (but particularly with regards to gay men) is how you're most likely to hear it used in Real Life.
A man dated by a lesbian to make her appear straight is known as 'a frock' in British English. A frock makes a woman appear feminine much as a beard makes a man appear masculine.
Gay men who marry The Beard do this generally as an elaborate refusal to come out of the closet. They "prove" it to themselves and others that they are not gay because they have a wife (that they never touch) so they most definitely are not leading a gay lifestyle.
Occasionally, someone's Beard will have to be someone they're in a Will They or Won't They? situation with. It usually ends up pushing them closer, but gets a Snap Back at the end.
Not to be confused with Growing the Beard, where a show significantly improves at some point, with the Playful Hacker of a technology startup, which consists (so they say) of The Beard and The Suit - the Beard handling the technology, the Suit handling both the business side, and ensuring that the Beard does not walk into traffic or excitedly explain his proprietary secrets to the first person who expresses an interest, or with Brian Wilson of the San Francisco Giants, whose nickname is The Beard.

In Love Hina this sort of thing happens a couple of times. Once when Keitaro plays boyfriend to Motoko in order to keep her from being forced back to run her family's dojo. The punch line is that when it is exposed, the sister decides to force them to get married. This also a different take on the Will They or Won't They? instance where the Beard (or the person using the Beard) is a rival to the other part of the Will They or Won't They? couple.

In the Rosario+Vampire manga, Tsukune is forced to play the beard for both Kurumu and Mizore at the same time, in order to convince their respective mothers that they have successfully seduced Tsukune.

In Maria†Holic Kiri decides to act as a lesbian beard to Kanako so that the jealous Schoolgirl Lesbians won't think that Kanako is involved the popular Ishima Ryuuken.

Hundred remains effectively Married to the Job and dismisses questions about his sexuality as unimportant.
Hundred: You have to understand, my mind sometimes makes...makes tactical decisions before the rest of me -

As does the 2004 Australian film Strange Bedfellows, which some have argued is not a coincidence.
The movie Can't Buy Me Love seems to play this trope straight. The main character, an unpopular nerd, helps a popular girl. In return, she pretends to be his girlfriend, so he can become more popular. It works almost too well. However, it subverts the trope when the girl falls in love with the nerd

When talking to Brandon, a friend dealing with torment and bullying due to his sexuality, she mentions how drastically a person's social status can change after a single juicy story and she agrees to pretend to sleep with him in order to convince the school he is straight.

Played less idyllically with Lord John and Bree from the later Outlander books. She's pregnant. He's gay, and a good many years her senior, as well as close friends with her dad. Considering the time period, it's not the unhappiest of matches— they get on pretty well after a while— but she doesn't seem to see him as much more than a human shield to cover up being vastly preggo. (Her way of persuading him to declare their engagement? Threaten to publicly out him. Which would mean public disgrace and death. Nobody said she wasn't a bitch.) Naturally, this doesn't last. She gets her man, and... well, he doesn't die. And that's good. Right? Don't worry. She gets... better-ish.

In Boston Legal, this is probably the best place to put the Denny and Alan marriage. Whilst there is no doubt they are not in a physical gay relationship, it is done to keep Denny's estate from being devoured by the government when he dies.
Only partly that; if anything Denny threw that in to sweeten the pot when first proposing to Alan. It's mainly done as Denny has started to suffer the effects of Alzheimer's disease, and Alan is the only person he trusts to care for him when Denny is no longer capable of looking after himself.
It also gives Alan spousal privilege, meaning that anything Denny tells Alan can remain secret/private as Alan cannot then be forced to reveal it in court.

A bizarre version of this trope appears in the Yu Gi Oh The Abridged Series full length episode of Zorc and Pals, when Zork (the giant, male, world-destroying god evil) pretends Bakura (who is arguably male)is his wife so that his mother will stop pestering him to get married. Hilarity ensues.
Naturally, The Simpsons did this. Homer and Selma had to fake marriage in order for Selma to be allowed to adopt a child. Apu and Marge did the same for Apu to get out of an arranged marriage.
And there's also the time Troy married Selma to resurrect his career in light of rumors of his fish-related "sexual abnormality".
And with Marge's other sister, Patty, her onetime relationship with Skinner might've been a retconned form of this, since Patty was eventually revealed to be a lesbian.
Considering the fact that the throw-away-line "There goes the last lingering thread of my heterosexuality" became accidental canon, it's entirely possible that Patty just "discovered" being gay, or was bisexual and now leans entirely towards women. Not an unrealistic situation.
Cleveland's boss from The Cleveland Show in one episode had a wife or at least was pretending to be and everyone thinks or knows that the boss is gay, later he asks for his beard and the "wife" shows up holding a Santa beard.
On King of the Hill, Dale's dad, Bug, tried to pull off the gay version of this trope when he was still in the closet. After Dale's wedding, Bug was flirting with an attractive Filipino caterer when Dale came into the room. He quickly grabbed, in his own words, "the nearest thing in a dress"—which happened to be the bride, Nancy. Twenty years of estrangement followed.
American Dad had an episode centering on this. The Smiths' gay neighbor Terry promises his partner Greg that he'll come out to his domineering father...but gets cold feet at the last minute and instead claims that Stan's wife Francine is his girlfriend, and that Stan and Greg are "the homos from across the street". Terry's dad seems to buy it, despite the obvious signs and Stan not doing a single thing to act gay.
English actor Charles Laughton married Elsa Lanchester (of The Bride of Frankenstein fame) yet continued to see men. One day, Lanchester came home to find Laughton on the sofa in flagrante delicto with a rent boy. She told him that she didn't mind, but went completely mute for three months in shock. She later told a friend that she'd had no idea Laughton was gay, but added, "Remember, he was a great actor!" They never divorced.
Because he married her so soon after first being accused of child molestation, Michael Jackson and Lisa Marie Presley's unsuccessful marriage was widely rumored to be this.
Liza Minelli is often (snarkily) said to be this for her last husband, David Gest.
A few years ago, Ian Wishart claimed that the then-Prime Minister of New Zealand, Helen Clark, was a lesbian with a gay husband. Controversy ensued.
According to the celebrity gossip blogs and their commenters, any woman who dates a handsome young Hollywood celebrity is a beard, because every last one of them is gay. Even when these men are serial monogamists who eventually marry, they're still gay, and the women they date are sniffily referred to as "the professional beard" and given the side-eye from there on in. Not surprisingly, Hollywood doesn't seem to have a large population of sexually active women (straight or lesbian) or conventionally unnattractive gay men, as the wishfully thinking gays and SlashRPF fangirls that populate these boards don't have any use for them,
Based on this, there's a persistent rumor that Taylor Swift is either gay or is the beard for all her boyfriends, because most of them have been suspected to be gay at some point, despite the fact half of the people she is supposedly the beard for have never actually dated her.
In China, because of the immense pressure to get married and have kids, somewhere around 80% of the gay population marries straight people. This has resulted in an interesting phenomenon where various places will host "fake-marriage markets" where gay and lesbian people can meet and look for someone who is willing to play the beard for them (and vice versa).
Played for laughs — English comedian Barry Cryer was classified "honorary gay" by his close friend Kenny Everett. Kenny insisted that his wife of 40 years and four kids were just a smokescreen.
Rock Hudson's three-year marriage to Phyllis Gates was done for this reason.
U.S. Representative Michelle Bachman is assumed to be one by the left-wing blogosphere for her husband, Marcus.
Fran Drescher lived this trope for 18 years before her husband found out he was gay. It became the basis for her show Happily Divorced, and she and her ex-husband are now very much Amicable Exes after a period of not speaking to each other.
