Count Nils Brahe (October 14, 1604 – November 21, 1632) was a Swedish soldier and younger brother of Per Brahe. He served with distinction under King Gustavus Adolphus, who regarded him as the best general in the Swedish army after Lennart Torstensson. At the beginning of the Battle of Lützen, Brahe received a wound to his knee. Two weeks later, at Naumburg, he died of that wound.
