Atimonan, officially the Municipality of Atimonan (Tagalog: Bayan ng Atimonan), is a municipality in the province of Quezon, Philippines. According to the 2020 census, it has a population of 64,260 people.

There are three plausible origins of the name of the municipality:

1. Atimon, an extinct tree alleged to have been prevalent in the area and had reportedly served many uses to the residents;
2. The Tagalog phrase atin muna, signifying a policy, unity of feeling, and sentiments among the residents that bolster their spirit in the fight against their enemies during that time; and
3. Simeona Mangaba, known to her town mates as Ate Monang, who was the older sister of the first town captain Francisco Mangaba and founder of the town. This is the most popular version.

Atimonan was founded by Simeona Mangaba on February 4, 1608, along the banks of the big Maling River, now known as Atimonan River.

Living along the riverbank, the people have always been prey to Moro attacks and so for fear of Moro reprisals, the inhabitants decided to transfer to Palsabangon, now a barrio of Pagbilao, Quezon. However, the people felt discontented in Palsabangon because the place abounds in wild crocodiles that from time to time disturbed them. So, in 1610, after two years of stay, they left the place and transferred to Babyaw, a part of Atimonan. They settled in Babyaw for almost 14 years but transferred again to another site called Minanukan for some unknown reasons. In 1635, they again transferred to another place called Bisita, but some families separated from the majority and settled in Yawe, now San Isidro in what is now Padre Burgos. The next year, when Simeona Mangaba learned of what happened to the original group of settlers, she, together with Fray Geronimo de Jesus, a Spanish friar, tried to unite them once more and convinced them to return to the place where it was first founded. The place is known now as Bagumbayan was during the time of Captain Pablo Garcia.

On January 1, 1917, barrio Laguimanoc was separated from Atimonan to become an independent municipality that is now known as Padre Burgos. On December 23, 1941, the occupying Japanese Imperial Army entered the towns through landing beaches in Atimonan.

Atimonan lies on the eastern shore of the province, 42 kilometers (26 mi) from Lucena and 172 kilometers (107 mi) southeast of Manila. Atimonan is bounded by the municipalities of Gumaca, Plaridel, Pagbilao and Padre Burgos.

Atimonan is politically subdivided into 42 barangays. Each barangay consists of puroks and some have sitios.

Tagultol Fishing Festival

The Tagultol Festival is an evolution of various cultural activities, practiced in previous years by Atimonanins. The Town and Patronal Fiesta every August 1 and 2 is simply celebrated with the usual parade, a cultural program, thanksgiving mass and procession. In 1981, during the administration of then Quezon Board Member and then Mayor of Atimonan Remedios V. Diestro, an activity was started – the Karakol. It is a fluvial parade done in the afternoon of the 2nd day of the fiesta. The boats traveled around Lamon Bay within the boundaries of the town proper headed by the Grand Boat where the patron—Nuestra Senora de Los Angeles—was aboard. There were singing, dancing and band playing, all in expression of gratitude to the Almighty for the year's bountiful catch. The parade then joined the religious procession and ended at the church.

Later, it was done in the morning after the thanksgiving mass at the Fishing Port and Boat Racing Competition followed after the Karakol. The creation of the Lupong Tagapangasiwa ng Kultura at Sining sa Atimonan (LUPTAKSA) under the leadership of Mr. Francisco T. Laude, a retired public school teacher, put new dimension and vigor to the town's cultural awareness and in the year 2003, the Tagultol Festival was finally launched. Tagultol, an old fishing method used by Atimonanins, was derived from the Tagalog word ugtol, meaning bounce. Tagultol fishing consists of a rectangular stone tied at the end of abaca strings dip in honey. Thorns of calamansi & similar plants with bait were tied 2 feet above the stone before dipping in water and moved in a bouncing movements. The festival is a five-day celebration starting July 29 until August 2. The celebration is an array of both cultural and sports activities, talent and beauty contests participated by community organizations and individuals and headed by the local government's culture and arts council (LUPTAKSA) and Atimonan Tourism Council.

The creation of the Tagultol Fishing Festival 15 years ago brought new vigor to Atimonan’s cultural awareness, as well as an expression of gratitude to the Almighty and the town’s patroness Nuestra Señora de los Angeles for the bountiful catch received by fisherfolk. The festival shows the old fishing method of “ugtol,” a Tagalog word meaning “bounce”. Tagultol fishing consists of a rectangular stone tied to a piece of abaca string dipped in honey to make it more resilient in salt water. The original music was composed by Francisco Laude, founder of Lupong Tagapangasiwa ng Kultura at Sining sa Atimonan.
