Elena Guerra (23 June 1835 – 11 April 1914) was an Italian Roman Catholic professed religious and the founder of the Oblates of the Holy Spirit.
Guerra dedicated her life to the education of girls and made it the sole focus of her religious life while also making a strong emphasis on devotion to the Holy Spirit.
To that end she sent a total of twelve private letters with Pope Leo XIII who held great esteem for Guerra's work to the point he issued three documents on it.
Leo XIII renamed Guerra's order further strengthening it though Guerra was forced to resign as the Superior General in August 1906 due to internal friction.Guerra was beatified on 26 April 1959 after the recognition of two miracles attributed to her intercession.
