Lazar Sočica (Serbian Cyrillic: Лазар Сочица; 1838 – 1910) was Piva chieftain, Montenegrin vojvoda, military commander and political leader, from the Old Herzegovina region.
Later, he opened the first stores in his hometown of Plužine, procured goods from coastal and Gacko traders, also organizing the export of cattle.
He soon became the richest man and chieftain in Piva region, which enabled him to be independent in his military activities, even from Prince Nikola I, who proclaimed him vojvoda.
When the area of Piva officially belonged to Montenegro by the decision of the Berlin Congress in 1878, Lazar Sočica remained the most influential military and political figure in the region.
His son Risto "Mujo" Sočica was also an influential political figure and the Ban of the Zeta banovina during the Kingdom of Yugoslavia.
