《peach》是IU演唱的一首歌曲，並由其本人填詞，收錄於2012年7月18日發行的專輯《Last Fantasy》中。完整的歌詞如下：
First I was like e-peach, e-peach,
then I'm on my way, peach
lookin' peach, feelin' peach
when I fell in love with you
So good so juicy
My peach on a tree
Your sweet scent's intoxicating
Your love's making me crazy
(Ah ah ah) My peach, peach, peach
(Ah ah ah) my sweetie, sweetie, sweetie
My heart is a basket of fruit
with every flavor filled to the brim
with every bite, I get peckish
Your love's so sweet that I want to spoon with it
Now it's ripe, now it's ready to be plucked
Now I want to stay up all night
When the sun sets, let's start making love
This peach skin is just like velvet
Oh, this peach skin is so soft and smooth
(Ah ah ah) My peach, peach, peach
(Ah ah ah) my sweetie, sweetie, sweetie
Oh my god, I'm in love with you
I'm so happy that I could burst into a song
Oh my god, I'm in love with you
How could you make such a delicious fruit?
Oh my god, I want to marry you now
Let's eat our peaches and make sweet music together forever
Peaches like this grow once in a lifetime
My god, they are all perfect from the core to the skin
But please don't slice it open just yet
Because this is the moment that you should cherish most
(Ah ah ah) My peach, peach, peach
(Ah ah ah) my sweetie, sweetie, sweetie
Oh my god, I'm in love with you...
Oh my god, I want to marry you now...
