Pugad Baboy (literally, "swine's nest" in Tagalog) is a comic strip created by Filipino cartoonist Apolonio "Pol" Medina, Jr. The strip is about a Manila community of mostly obese people - "fat as pigs", so to speak (baboy is Tagalog for pig).

It started appearing in the Philippine Daily Inquirer on May 18, 1988. It currently appears exclusively in the Inquirer line of newspapers (Broadsheet Inquirer and its free concise sister tabloid called Inquirer Libre and tabloids Bandera and Tumbok.) Its popularity has spawned numerous compilations, a live-action television series, and merchandise such as T-shirts and figurines.

The strip does not only showcase domestic life; occasionally, it features adventure, drama, and pure spoof sequences. More often, the strip mirrors the general sentiment of the Filipino people on relevant topics such as corruption in the government as well as Filipino pop culture. In this respect, the strip has been likened to Garry Trudeau's Doonesbury.Sometimes, political satire is woven into some ordinary strips and adventure stories.

Medina conceived the strip while working under contract in Iraq in 1986.In 1988, he peddled his strips to the Philippine Daily Inquirer. His strip, named after a friend's piggery in Bulacan, was accepted on the spot.

Medina originally spelled "Pugad Baboy" with a hyphen in the strip itself, though not in the title.

For many years, the newspaper strip was exclusively a black and white daily. A full-color Sunday strip in the same paper debuted on October 3, 2004. Before the tabloid Inquirer Libre debuted, the strip appeared exclusively in the Inquirer broadsheet.

In a strip published in September 2006, Medina commented on online life substituting for physical contact. He mentioned Wikipedia as one of the alternatives to library visits, the other being Google.

British English words are prevalent in the strip (like -ise words) and Medina uses these kinds of words in his own write-ups.

The characters are typically ageless, and their actual ages are usually vague. The few characters whose present ages are stated are Dagul (48), and the kids (8 or 9). Utoy and 'Adre are the only characters to have visibly aged in the strip through the years, barring flashbacks (Utoy first appeared as a baby; 'Adre has lately lost some of his hair). A "holdover hippie" from the Sixties, Bab nevertheless seems to be only in his twenties or thirties, which would be impossible in real time. In the early-1990s story arc Ang Hiwaga ng Dueñas (published in Pugad Baboy 4) the faith healer Mang Danilo, an old acquaintance, mentions that Bab was teenaged at the time of Woodstock (Bab immediately covers the faith healer's mouth as the word "Woodstock" is mentioned). A series of strips published in Pugad Baboy X (1998) implies that Bab is at least over 28 years old. In the same compilation, Tita Cel mentions that Jolen is 27 years younger than Bab and since the stock age of the Pugad Baboy children is 8-9, Bab is possibly 35-36.

One of the strip's running gags is the depiction (or at least the description) of Arabs having very foul body odor. Examples of this running gag are Kules' Saudi friend, which the former calls Lancaster (because the friend smells like the langka or jack fruit), and the stinky concentrated chemical agent PSSI (pawis ng singit ng sundalong Iraqi or Iraqi soldier's armpit sweat) mentioned in the story arc The Baguio Connection. This running gag is likely based on the author's personal experience. It is also reasonable, considering that the desert atmosphere in most Arab countries prevents their people from taking daily baths. Other such gags include the monotonous diet of chicken in Saudi Arabia (also likely based on personal experience), and Paltik's blatant aversion to the "coming of age" ritual of circumcision.

Medina usually voices out his takes on events, people and the like through Polgas and Mang Dagul. (Polgas is also recurringly shown as a comic strip artist, like his creator.) According to Medina, the characters he most identifies with are Polgas, Mang Dagul, and Utoy; like him, they wear earrings on their left ears.[12] Medina himself has even appeared once in the strip proper, holding a cartooning workshop in Palawan, though he avoids breaking the fourth wall by not referring to himself as the strip's creator.

As mentioned earlier in this article, the strip does not showcase domestic life alone as Medina has created story arcs which involve the various characters in adventure, dramatic or other plotted situations.

There is no standard as how long a story arc may last, since it can run from several weeks to a few months. The story arc is only titled when it is included in a compilation.
