San Pedro el Alto (Mixtec: Yuku Kuiꞌi, IPA: [ʒuku kʷiʔi]) is an agencia municipal of the municipality of San Mateo Peñasco, Oaxaca, Mexico.

In the local Mixtec language, San Pedro el Alto is called Yuku Kuiꞌi (IPA: [ʒuku kʷiʔi]; historically spelled Yucucuihi[3]), meaning "hill of fruit".

[7] The cacicazgo of San Pedro el Alto is the subject of a 16th-century manuscript called the Genealogy of Tlazultepec, currently kept in the Archivo General de la Nación.

The Genealogy shows the relationships between the caciques of San Pedro el Alto (then known as Tlazultepec), other Mixtec lineages, and their descendants, and was presented in 1597 in litigation over the succession to the cacicazgo.
