李商隐（813？～858？），字义山，号玉溪生，怀州河内（今河南泌阳）人，唐代诗人。开成进士，曾任县尉、秘书郎和东川节度使判官等职。因受牛李党争影响，被人排挤，潦倒终身。
其诗揭露和批判当时藩镇割据、宦官擅权和上层统治集团的腐朽糜烂，《行次西郊一百韵》、《有感二首》、《重有感》等皆著名。所作咏史诗多托古以斥时政，《贾生》、《隋宫》、《富平少侯》等较突出。无题诗也有所寄寓，至其实义，诸家所释不一。擅长律绝，富于文采，构思精密，情致婉曲，具有独特风格。然有用典太多，意旨隐晦之病。也工四六文。有《李义山诗集》，文集已散轶，后人辑有《樊南文集》、《樊南文集补编》。
蝉
本以高难饱，徒劳恨费声。
五更疏欲断，一树碧无情。
薄宦梗犹泛，故园芜已平。
烦君最相警，我亦举家清。
A Cicada
Pure of heart and therefore hungry，
All night long you have sung in vain—
Oh，this final broken indrawn breath
Among the green indifferent trees！
Yes，I have gone like a piece of drift wood，
I have let my garden fill with weeds...
I bless you for your true advice
To live as pure a life as yours.
风雨
凄凉宝剑篇，羁泊欲穷年。
黄叶仍风雨，青楼自管弦。
新知遭薄俗，旧好隔良缘。
心断新丰酒，销愁又几千。
Wind and Rain
I ponder on the poem of The Precious Dagger.
My road has wound through many years.
Now yellow leaves are shaken with a gale；
Yet piping and fiddling keep the Blue Houses merry.
On the surface，I seem to be glad of new people；
But doomed to leave old friends behind me，
I cry out from my heart for Xinfeng wine
To melt away my thousand woes.
北青萝
残阳西入崦，茅屋访孤僧。
落叶人何在，寒云路几层。
独敲初夜磬，闲倚一枝藤。
世界微尘里，吾宁爱与憎。
North among Green Vines
Where the sun has entered the western hills，
I look for a monk in his little straw hut；
But only the fallen leaves are at home，
And I turn through chilling levels of cloud
I hear a stone gong in the dusk，
I lean full-weight on my slender staff
How within this world，within this grain of dust，
Can there be any room for the passions of men？
