力康鸡，又称莱亨鸡，来航鸡,是一种源自意大利托斯卡尼的鸡，1853年引进至北美洲。1865年以原产地港口城市里窝那（英文称Leghorn）得名。

颜色以白色为主，但也有其他色系。以每年高达280枚产蛋量，以及白色的蛋壳而成为著名的蛋用鸡，但由于重量较轻故不被视为肉用鸡种。华纳兄弟的卡通片《乐一通》当中的角色莱亨鸡福亨是一只力康鸡。

The Leghorn (/ˈlɛɡhɔːrn/ or UK /lɛˈɡɔːrn/; Italian:Livorno or Livornese) is a breed of chicken originating in Tuscany, in central Italy. Birds were first exported to North America in 1828 from the port city of Livorno, on the western coast of Tuscany. They were initially called "Italians", but by 1865 the breed was known as "Leghorn", the traditional anglicisation of "Livorno". The breed was introduced to Britain from the United States in 1870. White Leghorns are commonly used as layer chickens in many countries of the world. Other Leghorn varieties are less common.
