Duke Ling of Jin (晉靈公 Jìn Líng Gōng), personal name Ji Yigao, was from 620 to 607 BC the duke of the Jin state. He ascended the throne with the support of his regent, Zhao Dun (Viscount Xuan of Zhao).

In 607 BC, 14 years after ascending the throne, Duke Ling had reached adulthood and become increasingly despotic. He was known to have had his chef killed for not cooking his bear paws well. Zhao Dun, who enjoyed a reputation for integrity and incorruptibility, tried to stop him. Resentful of Zhao Dun's influence, Duke Ling tried to have Zhao Dun assassinated. Zhao Dun managed to escape, and on 19 August, his half-brother Zhao Chuan (趙穿) rebelled and killed Duke Ling. Zhao Dun and Zhao Chuan then installed Duke Ling's uncle, Duke Cheng, on the throne of Jin.

晉靈公（？ - 前607年），姬姓，名夷皋，春秋時期晉國君主。晉襄公之子，母親為穆嬴。

晉靈公即位時年幼，由趙盾輔政。長大後，不行君道，荒淫無道，以重稅來滿足奢侈的生活（厚斂以彫牆）。

他在高台上用彈弓射行人，觀看他們躲避彈丸的樣子。一次因為熊掌燉得不夠爛，就把廚師殺掉，把屍體裝到筐子裏，並讓宮女載到朝廷示眾。種種暴行，不可勝數。大臣趙盾多次勸諫，使晉靈公很反感，暗中派刺客鉏麑刺殺趙盾。鉏麑卻感嘆趙盾忠君愛民，自己一頭撞樹而死。

晉靈公又設宴招待趙盾，暗中埋伏士兵，打算趁機殺死他。趙盾的車右武士提彌明得知此事，趕忙跑到宮殿，扶著趙盾退下。靈公使一條狗來咬趙盾，提彌明把狗殺死，提彌明後來被士兵所殺。

前607年趙穿攻殺靈公於桃園，趙盾派趙穿往周迎公子黑臀，是為晉成公，太史董狐寫道，「趙盾弒其君，以示於朝。」

在位期間執政為：趙盾、先克、郤缺、荀林父、先蔑、先都、箕鄭、欒盾、胥甲、臾駢。

晉靈公墓現為山西省文物保護單位。
