Nikola Šarčević (Serbian Cyrillic: Никола Шарчевић) (born July 9, 1974, in Örebro, Sweden) is the bassist, vocalist, and primary songwriter in the punk rock band Millencolin. He lives in Gothenburg, Sweden with his wife Lisa, and three daughters.

Lock-Sport-Krock was Šarčević's first solo album. The title comes from the name of an imaginary football team that he and his brother pretended to play in when they were young. His solo work is mostly composed of Folk Rock and Country Music.
