The 1892 Session of the Legislature of the Hawaiian Kingdom, also known as the Longest Legislature, was a period from May 28, 1892, to January 14, 1893, in which the legislative assembly of the Hawaiian Kingdom met for its traditional bi-annual session. This unicameral body was composed of the upper House of Nobles and the lower House of Representatives. This would be the first session during the reign of Queen Liliʻuokalani and the last meeting of the legislative assembly during the Hawaiian monarchy. Three days after the prorogation of the assembly, many of the political tension developed during the legislative debates and the queen's attempt to promulgate a new constitution while her legislators were not in session led to the overthrow of the Hawaiian Kingdom on January 17, 1893.
