Fermentelos is a civil parish in the municipality of Águeda in the district of Aveiro, Portugal. The population in 2011 was 3,258, in an area of 8.58 km. A minor village within an independent parish, the area was elevated to the status of vila (English: town) on 5 May 1928.

A popular legend tells of three brothers, who had become lost in the fog, as they navigated the River Cértima and were guided to the Pateira. Impressed by the beauty of the region, they decided to stay and fished the waters of the river to sell to the neighboring villages. The three brothers (André, Domingos and Tomé) then tried to give the area a name, and began to argue. The youngest proposed Ferment and quickly got into conflict with the other two, leading to a duel. From the Portuguese name for ferment+duel developed the name Fermentelos.

The first record of Fermentelos (1050) came from inventories by Gonçalo Viegas and his wife Flâmula, that elaborated on the significance of the vila and peoples. By 1077, a similar inventory was carried out, but this time included the possessions of Paio Gonçalves' lands. Around this time a reference to a Faramontanellos situated along the margins River Cértima appeared in document 549 in Diplomata et Charte.

From the earliest references, there were horse-mounted huntsmen, who paid the donatários a fee to hunt on lands designated for hunting, which were known as Foramontanos. During King Afonso II's inquiries in 1220, the local name had evolved to Foramontaelos, whose significance was the base terms fora+monte (likewise montaria, monteiro), which had its meaning in "mounted hunting on horseback". When these lands were small, or if the existence of games was little, the referred to these areas as Foramontanelos. These adjectives evolved into proper nouns, Foramontões e Foramontanelos, and finally appeared in documents, such as the Manuelino foral.

The King's investigations identified a large quality and quantity of cultivated goods, yet there is no reference to inhabitants, even as adjacent territories were populated. Foramontaelos was a village and all royal"; it was a royal domain that produced wheat, wine, a chickens, eggs, cheese and butter, but little was known if inhabitants only cultivated these lands, or resided within their boundaries.

King Manuel incorporated Formentelos into the now extinct municipality of Óis da Ribeira on 2 June 1516, when he established its foral. The area of Formentelos was designated as Mata Real de Perrães, Paradela, e Louredo (English: King's Land of Perrães, Paradela, e Louredo), and were direct neighbors of lands occupied by the Bishop of Coimbra and the Convent of Lourã. By the end of the 15th century, the King was obliged to entrust in Anrique de Almeida, his sheriff in Aveiro, with the caretaker-ship of the Mata de Perrães, in order to secure his local lands from vagrants who took deer and grazed their pigs on the lands. In 1626, Lourenço de Almeida Alcoforado, son of the niece of Anrique de Almeida, who was inheritor of the royal privileges, sold these rights to Diogo de Teles Castel-Branco on 17 April 1626, in the presence of the notary Belchior Correia de Vasconcelos.

In 1672 a formal site plan of the Mata Real was undertaken by the King, concluded that the land designated as the King's land had diminished considerably; owing to the necessity to examine these domains by boat, it was determined that a portion had become a part of the Pateira de Fermentelos.

The caretaker-ship of Fermentelos continued to be the responsibility of the family of Diogo de Teles since 1626, until the middle of the 19th century. Afterward the House of Atalho, which was always responsible for justice, resolving property disputes and collecting rents took over the role of the Crown's Foreign Judge (Portuguese: Juíz de Fora). During the Liberal Wars, it was inherited by a noblewoman, whose husband was a proponent of Miguel of Portugal. Even after the 1822 and 1834 conflicts, she supported absolutist forces and their local interests, and forgot these rebels' rents.

Until 1832, the parish of Fermentelos was governed by noblemen under the auspicious of the Foreign Judge, a ceremonial title-holder that administered various lands owned by the monarch. Ferementelos became an independent parish when on 16 May 1832, the laws were abolished and a system of parishes, municipalities and districts were instituted that eliminated many of the titles and honorifics associated with the ruling-classes, including the Juizes de Fora and local sheriffs.

The village of Fermentelos was granted a parish charter on 5 May 1928.
