Orléans is a provincial electoral district in eastern Ontario, Canada.

It elects one member to the Legislative Assembly of Ontario.

It was created in 1999 from Prescott and Russell, Carleton East and Ottawa—Rideau.

The electoral district was initially named Carleton—Gloucester, and the June 1999 provincial election was conducted by Elections Ontario under that name, but it was known as Ottawa—Orleans by the time of the October 2003 provincial election.

For the 2018 election, the riding was renamed Orléans, and lost the neighbourhood of Beacon Hill South from Ottawa—Vanier, and will gain the Cardinal Creek area from Glengarry—Prescott—Russell and the rural area surrounding Carlsbad Spring from parts of Glengarry—Prescott—Russell and Nepean—Carleton.
