San Miguel de Velasco (Spanish: [ˈsan miˈɣel de βeˈlasko], locally [ˈsaŋ miˈɰel de β̞eˈlahko], Migueleño Chiquitano: [samĩˈj̃ɛːɾɛ̥]) or simply San Miguel is a town in the Santa Cruz Department, Bolivia.

[3][4] San Miguel de Velasco is home to the speakers of Migueleño Chiquitano, a critically endangered variety of the Chiquitano language which is now remembered only by several dozen elderly people.

[7] In San Miguel de Velasco, Catholic homilies are traditionally recited in an early form of Migueleño Chiquitano on certain religious occasions.

This practice can be traced back to the Jesuit reductions of the 18th century, and the texts of the homilies have been transmitted (both orally and in the written form) across generations.

[8] The homilies have been extensively studied by Severin Parzinger, who has published a compilation thereof.
