Saint Rosa Francisca Dolors Molas Vallvé (24 March 1815 – 11 June 1876) was a Spanish Roman Catholic nun.
Following her solemn profession as a nun she assumed the name of "Maria Rosa" and also established the religious congregation known as the Sisters of Our Lady of Consolation.
Vallvé decided that her order would be devoted to women and for service to the poor who mostly required aid.
Pope Paul VI beatified her in mid 1977 and she was beatified in late 1988 as a result of the recognition of three miracles attributed to her intercession.
