Chôros No. 10 ("Rasga o Coração") is a work for chorus and orchestra written in 1926 by the Brazilian composer Heitor Villa-Lobos. It is part of a series of fourteen numbered compositions collectively titled Chôros, ranging from solos for guitar and for piano up to works scored for soloist or chorus with orchestra or multiple orchestras, and in duration up to over an hour. Chôros No. 10 is of moderate length, one performance recorded by the composer lasting just under thirteen minutes.

Chôros No. 10 falls into two main sections, the first for orchestra alone, the second adding a mixed choir. The question of the further subdivision of part one is less certain. It can be regarded as falling into two subdivisions: a rhythmically energetic impetus (page numbers 1–18) and an impressionistic nocturne, with the tempo marking Lent (page numbers 18–35).

The composer describes Amazonian birdsong as an important source of motivic material in the opening portion of Chôros No.10. The first thematic fragment, presented in the flute in bar 3, is "a transfigured melodic cell characteristic of the song of a rare bird of the Brazilian forests, called in some places Azulão da mata"—in English called blue-black grosbeak.
