Blessed Lindalva Justo de Oliveira (20 October 1953 - 9 April 1993) was a Brazilian Roman Catholic professed religious and a professed member of the Vincentian Sisters.
Oliveira worked at a shelter where she was killed in 1993 after a man obsessed with her stabbed her 44 times when she refused his unwanted advances.Oliveira's beatification received the approval of Pope Benedict XVI who determined that she was killed "in defensum castitatis" - the defense of her vow for being chaste.
