Multinational Brigade South-East (MN BDE SE) is an infantry brigade of the Romanian Land Forces. During the 2016 Warsaw summit, NATO secretary general Jens Stoltenberg announced that a Romanian Army brigade was going to be transformed into a NATO Multinational Brigade. Following a meeting of the Romanian Supreme Council of National Defence in September 2016, the President of Romania announced that the 2nd Infantry Brigade was to take the role of the multinational brigade.

MN BDE SE was declared fully operational by the Deputy Commander of the Allied Land Command in 2018 following the evaluation exercise Scorpions Fury 2018.
