The Leader of the Opposition in the Odisha Legislative Assembly is the politician who leads the official opposition in the Odisha Legislative Assembly.

Official Opposition[1] is a term used to designate the political party which has secured the second largest number of seats in the assembly.

In order to get formal recognition, the party must have at least 10% of total membership of the Legislative Assembly.

A single party has to meet the 10% seat criterion, not an alliance.
