The Adorers of the Blood of Christ (Latin: Sorores Adoratrices Pretiosissimi Sanguinis) are a Catholic centralized religious institute of consecrated life of Pontifical Right for women founded by Maria De Mattias in 1834.

The Institute of the Sisters Adorers of the Blood of Christ was established by Maria De Mattias, on March 4, 1834, in Acuto, Italy.

Before long she was joined by others and schools were opened in the small towns of the Papal States and the Kingdom of Naples.

[4] In 1933, the Adorers of the Blood of Christ founded Sacred Heart Junior College in Wichita which eventually became Newman University.

[10] In July 2017, in Columbia, Pennsylvania, the Sisters went to court to oppose the construction of the Atlantic Sunrise pipeline on a right-of-way through their land.
