18th Birthday Poems

Appeal to your loved one’s poetic side with these beautiful verses taking the place of the usual birthday wishes.

  1. Happy Birthday
    This is a very special day
    Your friendship has filled my life far beyond what words can say
    I give thanks to the Lord for sending you my way
    That’s why we celebrate today
    Happy Birthday!
    – Udiah (witness to Yah)
  1. A Happy Birthday
    This evening, I sat by an open window
    and read till the light was gone and the book
    was no more than a part of the darkness.
    I could easily have switched on a lamp,
    but I wanted to ride this day down into night,
    to sit alone and smooth the unreadable page
    with the pale gray ghost of my hand.
    – Ted Kooser
  1. A Birthday
    My heart is like a singing bird
    Whose nest is in a water’d shoot;
    My heart is like an apple-tree
    Whose boughs are bent with thickset fruit;
    My heart is like a rainbow shell
    That paddles in a halcyon sea;
    My heart is gladder than all these
    Because my love is come to me.Raise me a dais of silk and down;
    Hang it with vair and purple dyes;
    Carve it in doves and pomegranates,
    And peacocks with a hundred eyes;
    Work it in gold and silver grapes,
    In leaves and silver fleurs-de-lys;
    Because the birthday of my life
    Is come, my love is come to me.
    – Christina Rossetti
  1. Birthday Lights
    Light bulbs on a birthday cake.
    What a difference that would make!
    Plug it in and make a wish,
    then relax and flip a switch!
    No more smoke
    or waxy mess
    to bother any birthday guests.
    But Grampa says, “it’s not the same!
    Where’s the magic?
    Where’s the flame?
    To get your wish without a doubt,
    You need to blow some candles out!”
Quick tip
If your teen is a poem fanatic, writing a personalized poem for them could be a lovely birthday gift.
