恰卡·祖鲁（祖鲁语：Shaka Zulu，约1781年－1828年9月22日）或恰卡·辛赞格科纳（Shaka kaSenzangakhona），，又译夏卡、沙卡，非洲祖鲁族首领，祖鲁王国创建者。

他是Senzangakhona kaJama的私生子，被父亲放逐。在姆特瓦（Mthethwa）首领丁吉斯瓦约（Dingiswayo）的帮助下，他成为了祖鲁族的首领。后来通过战争，逐步征服了各地部落，创建祖鲁王国。

1827年，他的母亲Nandi病逝，此后他变得越来越残暴。1828年左右，他被同父异母弟弟丁冈和Mhlangana谋杀，随后丁冈杀死了Mhlangana，夺取了王位。

Shaka kaSenzangakhona (circa 1787 – 22 September 1828), also known as Shaka Zulu (Zulu pronunciation: [ˈʃaːɠa]), was one of the most influential monarchs of the Zulu Kingdom.

He was born near present-day Melmoth, KwaZulu-Natal Province. According to tradition, Shaka was conceived during an act of what began as ukuhlobonga, a form of sexual foreplay without penetration allowed to unmarried couples, also known as "the fun of the roads" (ama hlay endlela), during which the lovers were "carried away".
