The 1846 Louisiana gubernatorial election was the first of two elections to take place under the Louisiana Constitution of 1845. The new constitution abolished the provision in the 1812 constitution that required a gubernatorial candidate to win a vote of the legislature to get elected, leaving the final decision up to the people. The new constitution also cut incumbent Governor Alexandre Mouton's term short by one year thus moving the election from July 1846 to January 1846 with the inauguration of the new governor in February.
