Samson Morpurgo ben Joshua Moses (1681 – 12 April 1740) was an Italian rabbi, physician, and liturgist.
At the end of this work was printed a satire upon the cabalists by Jacob Frances, on account of which Morpurgo was persecuted by the rabbis of Padua.
Morpurgo enjoyed much consideration as a distinguished rabbi; his objections to certain rabbinical decrees are to be found in Giovanni Bernardo De Rossi, "Bibliotheca Antichristiana," p. 63; and an approbation of his, of 1716, was inserted by Isaac Lampronti in his "Paḥad Yiẓaḳ," i.
Morpurgo left a number of responsa on the four parts of the Shulḥan 'Aruk, which were published, with notes and preface, by his son Moses Ḥayyim Shabbethai (Venice, 1743).
He was also the author of a prayer beginning "Anna ha-El ha-Gadol ha-Gibbor weha-Nora," to be recited by persons visiting the cemetery.
