The Sisters of Mary Morning Star, also called the Sisters of Maria Stella Matutina, are a Roman Catholic religious institute of non-cloistered contemplative sisters. The sisters do not perform missionary or educational work, focusing primarily on prayer and spiritual guidance. 
The order was formed in June 2014 in Bergara, Spain as an association of the faithful under Bishop Jose Ignacio Munilla of San Sebastian. The initial associations consisted of members who had broken off from the Community of Saint John, an order based in France, after feeling the priests of the community were overly controlling of the sisters. It has about 300 members across fourteen dioceses and thirty convents. The order's generalate is located in Parma, Italy.

The Texas priory has worked with death row prisoners in Gatesville, Texas since December 2021. Of the seven women the sisters have worked with (including Kimberly Cargill, Brittany Holberg, Melissa Lucio, and Darlie Routier), six chose to convert to Catholicism and to become oblates.
