刘长卿（709～780），字文房，河间（今河北省河间县）人，唐代诗人。开元二十一年（733年）进士，因性格刚直，曾得罪权贵而被诬入狱，官终于随州刺史。
他是大历十才子之一，他的诗歌，有的反映安史之乱以后人民生活的痛苦，有的是写遭谗被谪之后的愤懑，而更多的是写山水隐逸闲情，使得风格谨严凝练，圆熟细密，善于以画入诗，尤其是五言律诗及绝句，在当时颇负盛名，自称为“五言长城”。
江州重别薛六柳八二员外
生涯岂料承优诏，世事空知学醉歌。
江上月明胡雁过，淮南木落楚山多。
寄身且喜沧洲近，顾影无如白发何。
今日龙钟人共老，愧君犹遣慎风波。
On Leaving GuijiangAgain to Xue and Liu
Dare I，at my age，accept my summons，
Knowing of the world’s ways only wine and song？
Over the moon-edged river come wild-geese from the Tartars；
And the thinner the leaves along the Huai，the wider the southern mountains…
I ought to be glad to take my old bones back to the capital，
But what am I good for in that world，with my few white hairs？
As bent and decrepit as you are，I am ashamed to thank you，
When you caution me that I may encounter thunderbolts.
长沙过贾谊宅
三年谪宦此栖迟，万古惟留楚客悲。
秋草独寻人去后，寒林空见日斜时。
汉文有道恩犹薄，湘水无情吊岂知。
寂寂江山摇落处，怜君何事到天涯。
On Passing Jia Yi’sHouse in Changsha
Here，where you spent your three years’exile，
To be mourned in Chu ten thousand years，
Can I trace your footprint in the autumn grass—
Or only slanting sunlight through the bleak woods？
If even good Emperor Wen was cold-hearted，
Could you hope that the dull River Xiang would understand you，
These desolate waters，these taciturn mountains，
When you came，like me，so far away？
