Blessed Giulia Crostarosa (31 October 1696 – 14 September 1755) was an Italian Roman Catholic nun who founded the Order of the Most Holy Redeemer (Redemptoristines).
She reported a series of visions that led to the establishment of a congregation with its own rule.
She assumed the religious name of "Maria Celeste" when she became a professed nun.
Pope Francis declared her to be Venerable for her life of heroic virtue on 3 June 2013; a miracle attributed to her intercession was approved in 2015 which paved the path for her beatification, which took place on 18 June 2016 in Foggia with Cardinal Angelo Amato presiding on the behalf of the pope.
