莎士比亚的十八首诗包括以下几首著名的十四行诗：

Sonnet 18

Shall I compare thee to a summer's day？

Thou art more lovely and more temperate:

Rough winds do shake the darling buds of May,

And summer's lease hath all too short a date:

Sometime too hot the eye of heaven shines,

And often is his gold complexion dimm'd；

And every fair from fair sometime declines,

By chance, or nature's changing course, untrimm'd；

But thy eternal summer shall not fade,

Nor lose possession of that fair thou ow'st；

Nor shall Death brag thou wander'st in his shade,

When in eternal lines to time thou grow'st.

So long as men can breathe or eyes can see,

So long lives this, and this gives life to thee.

Sonnet 29

Sonnet 73

Sonnet 116

When in Disgrace with Fortune and Men's Eyes

Full Many a Glorious Morning Have I Seen

My Mistress' Eyes are Nothing Like the Sun

Let Me Not to the Marriage of True Minds

When to the Sessions of Sweet Silent Thought

That Time of Year Thou Mayst in Me Behold

No Longer Mourn for Me When I Am Dead

Not Marble nor the Gilded Monuments

O Mistress Mine, Where Are You Roaming？

Fear No More the Heat o' the Sun

Blow, Blow, Thou Winter Wind

Under the Greenwood Tree
