Agnes (1179 – 8 October 1184) was a princess of the House of Hohenstaufen. She was the youngest child of Frederick I, Holy Roman Emperor, and his second wife, Beatrice of Burgundy.{{sfn|Freed|2016|p=417}}

Agnes was born in early 1179.{{sfn|Freed|2016|p=417}}{{harvnb|Loud|2025}}, n.p. in [https://books.google.ca/books?id=JTA0EQAAQBAJ&pg=PT126 preview]. Her brother Philip had been born around February 1178, when Beatrice and Frederick were in Genoa.{{sfn|Freed|2016|pp=415–417}} The date of her birth can be deduced from her young age at death and the established timeline for the births of her siblings. Only one medieval source, {{ill|Johann von Mutterstadt|de}}, mentions her name. In all other medieval sources, she is referred to only as a daughter of Frederick or Beatrice.{{sfn|Assmann|1977|p=453}}

Agnes was betrothed at a young age to Emeric, the son of King Béla III of Hungary. As Emeric was born in 1174, they were both children at the time, although he was a few years older. Owing to her death, the marriage never took place.{{sfn|Assmann|1977|p=453}} The purpose of the marriage, from Béla III's perspective, was to secure peace and friendship in the west while pursuing an expansionist policy against Byzantium in the east.{{sfn|Makk|1989|p=116}} In 1184, sources record the proposed marriage of an unnamed daughter of Frederick I to Richard the Lionheart, but this was one of Agnes' older sisters, whose name is uncertain.{{harvnb|Assmann|1977|pp=453–454}}, notes that the dates are inconsistent, since the marriage project with Richard began only in September and yet Agnes was betrothed to someone else at her death. The age discrepancy between her and Richard also makes the project suspect. {{harvnb|Freed|2016|p=14}}, distinguishes the two daughters, but assigns the proposed marriage with Richard to Agnes on p. 451.

Agnes died on 8 October 1184 and was buried alongside her in Speyer Cathedral.{{sfn|Freed|2016|p=5}} Two separate sources report on the close timing of the deaths of Agnes and her mother. The {{ill|Cronica sancti Petri Erfordensis moderna|lt=Chronicle of Saint Peter of Erfurt|de|Cronica S. Petri Erfordensis moderna}} records how she was still a little girl ({{lang|la|licet parvula}}) and was betrothed ({{lang|la|desponsata}}) to the son of the king of Hungary at the time of her death.{{sfn|Assmann|1977|p=451}} The {{ill|Marbach Annals|de|Marbacher Annalen}} record that she died not long before 1 November 1184 and Beatrice not long after, noting also that she was betrothed at the time of her death.{{sfn|Assmann|1977|p=451}} Possibly both Agnes and Beatrice were ill in September, when Barbarossa set out on his sixth Italian expedition, since neither accompanied him.{{sfn|Assmann|1977|p=457}}

In his chronicle of the bishops of Speyer, Johann von Mutterstadt, who died in 1472, reports how, during the opening of a tomb for King Adolf of Germany in Speyer Cathedral, a small casket was found containing the body of a young girl wrapped in silk. The casket was decorated with the effigy of a little girl and contained the epitaph: "On 8 October, Agnes, daughter of King Frederick the Emperor, died" ({{lang|la|Octavo idus octobris Agnes filia regis Friderici imperatoris obiit}}).{{sfn|Assmann|1977|pp=452–453}}
