The Dahomey Amazons (Fon: Agojie, Agoji, Mino, or Minon) were a Fon all-female military regiment of the Kingdom of Dahomey (in today's Benin, West Africa) that existed from the 17th century until the late 19th century. They were the only female army in modern history. They were named Amazons by Western Europeans who encountered them, due to the story of the female warriors of Amazons in Greek mythology.

The emergence of an all-female military regiment was the result of Dahomey's male population facing high casualties in the increasingly frequent violence and warfare with neighbouring West African states. This led to Dahomey being one of the leading states in the slave trade with the Oyo Empire, which used slaves for commodity exchange in West Africa until the slave trade in the region was ended through British pressure. The lack of men likely led the kings of Dahomey to recruit women into the army. The formation of a female-only army unit was a retaliation and maneuver around the forced tribute of male slaves to Oyo each year.

King Houegbadja (who ruled from 1645 to 1685), the third King of Dahomey, is said to have originally started the group which would later become the Mino as a corps of elephant hunters called the gbeto. The gbeto may even predate Houegbadja, as there is a tradition where he merely organized pre-existing groups into a corps, and another were the gbeto themselves offered to serve the king.

Houegbadja's daughter Queen Hangbe (ruling from 1716 to 1718) established a female bodyguard. European merchants recorded their presence. According to tradition, her brother and successor King Agaja successfully used them in Dahomey's defeat of the neighbouring kingdom of Savi in 1727. The group of female warriors was referred to as Mino, meaning "Our Mothers" in the Fon language, by the male army of Dahomey. Other sources contest the claim that King Agaja's older sister Queen Hangbe was the ruler to establish the units, some even going so far as to question whether or not Queen Hangbe actually existed.

From the time of King Ghezo (ruling from 1818 to 1858), Dahomey became increasingly militaristic. Ghezo placed great importance on the army, increasing its budget and formalizing its structure from ceremonial to a serious military. While European narratives refer to the women soldiers as "Amazons", they called themselves ahosi (king's wives) or Mino (our mothers). This group aided Ghezo in the Battle of Ketu and Sabe against the Oyo Empire

Ghezo recruited both men and women as soldiers from foreign captives. Female soldiers were also recruited from free Dahomean women, with some enrolled from as young as eight years of age. Other accounts indicate that the Mino were recruited from among the ahosi ("king's wives"), of which there were often hundreds. Some women in Fon society became soldiers voluntarily, while others were involuntarily enrolled if their husbands or fathers complained to the king about their behaviour.

Membership among the Mino was supposed to hone any aggressive character traits for the purpose of war. During their membership they were not allowed to have children or be part of married life (though they were legally married to the king). Many of them were virgins. The regiment had a semi-sacred status, which was intertwined with the Fon belief in Vodun. Oral Dahomean tradition holds that, upon recruitment, the Amazons were subjected to female circumcision.

The Mino trained with intense physical exercise. They learned survival skills and indifference to pain and death, storming acacia-thorn defences in military exercises and executing prisoners. Discipline was emphasised.
