Michael Ostrog (c. 1833 – after 1904) was a Russian criminal and Jack the Ripper suspect, first proposed in a memorandum by Sir Melville Macnaghten in 1894.
Ostrog was a swindler with a profuse police record who perpetrated multiple scams and frauds, but it was never proven that he committed any murders. According to 21st century investigations, during 1888 he was imprisoned in France, and such a circumstance would rule out his participation in any of the Whitechapel murders.
