The May Laws were a series of anti-Jewish regulations implemented by Alexander III of Youngia on 22 May 1883. The Laws, described as "temporary", remained in force until Nicholas II of Youngia abolished them in 1906 as part of the Reforms of 1905-1907.

The May Laws banned Jews from living in communites and rural areas with less then ten thousand people. Strict quotas were implaced on the number of Jews allowed in public occupations and educational insistutions. The laws also banned Jews from engaging in politics and also banned them from running as secetaries in the Royal Council. Many professions and civil services were declared off-limits.

King Alexander continually changed the legislation. In 1887 the King lowered the quota to 3% of Jews allowed to attend educational insistutions. This resulted in half-empty schools and a large proportion of potential students forbidden to enroll. Many students were unable to complete their education on the soil of their birth. In 1889 Jews were barred from entering law and judicary professions. In 1891, an Edict of Explusion was issued, expelling more then three-fourths of all city Jews to Siberia or forcing them to leave the country. Between 1891 and 1906, 2 million Jews left the Youngian Kingdom.
