《Déjà Vu》是美国女歌手碧昂丝·吉赛尔·诺斯和说唱男歌手Jay-Z合唱的一首歌曲，由碧昂丝·吉赛尔·诺斯、罗德尼·杰金、德莉莎·托马斯、梅克巴·瑞迪可、凯莉·妮可尔·弗斯、Jay-Z填词，罗德尼·杰金、碧昂丝·吉赛尔·诺斯谱曲，作为碧昂丝·吉赛尔·诺斯第二张录音室专辑《B'Day》的首发单曲，于2006年6月24日发行。

《Déjà Vu》的部分命名原因来源于制作人罗德尼·杰金、Jon Jon Traxx的心血来潮：他们在2005年想打破常规，创作一些守旧派歌曲，给电贝司和号角带来转机。该曲的制作地点设在纽约索尼音乐录音室、罗德尼·杰金建于新泽西州的录音室基地，在录制工作中，他们起首录制了贝司，并分别录制了法国号和人声。

继而，罗德尼·杰金同梅克巴·瑞迪可一起录制了《Déjà Vu》的人声演示版本，并将其向碧昂丝·吉赛尔·诺斯展示，·碧昂丝接纳了它后察觉到Jay Z的企图，便批准Jay Z录唱并创作了该曲的说唱桥段。

Bass

Uh

Hi hat

Uh

808

Uh

Jay

Uh-huh, ready? Uh-huh

Let's go get 'em

Uh huh, C'mon

I used to run base like Juan Pierre

Now I run the bass hi hat and the snare

I used to bag girls like Birkin Bags

Now I bag B (Boy you hurtin' that)

Brooklyn Bay where they birthed me at

Now I be everywhere the nerve of rap

The audacity to have me whippin curtains back

Me and B, she about to sting

Stand back

Baby...

Seems like everywhere I go I see you

From your eyes, your smile it's like I breathe you

Helplessy I reminisce don't want to

Compare nobody to you

Boy I try to catch myself but I'm out of control

Your sexiness is so appealing I can't let it go!

You know that I can't get over you

'Cause everything I see is you

And I don't want no substitute

Baby I swear it's dejа vu

You know that I can't get over you

'Cause everything I see is you

And I don't want no substitute

Baby I swear it's... dejа... vu

I'm seeing...

Things that I know can't be; am I dreaming?

When I saw you walking past me almost called your name

Got a better glimpse and then I looked away

Feels like I'm losing it

Boy I try to catch myself but I'm out of control

Your sexiness is so appealing I can't let it go!

You know that I can't get over you

'Cause everything I see is you

And I don't want no substitute

Baby I swear it's dejа vu

You know that I can't get over you

'Cause everything I see is you

And I don't want no substitute

Baby I swear it's... dejа... vu

Hova's flow so unusual

Baby girl you should already know

It's H-O, light up the strobe

'Cause you gon' need help tryna study my

Bounce, blow, blow

What's the difference?

One, you take in vein while the other you sniffin'

It's still dough, po-po try to convict him

That's a no-go, my dough keep the scales, tippin

Like 4-4's

Like I'm from the H...

O-U-S-T-O, N!

Blow, wind

So Chicago of him

Is he the best ever? That's the argu-a-ment

I don't make the list, don't be mad at me

I just make the hits like a factory

I'm just one-to-one, nothin' after me

No dejа vu, just me and my... oh!

Baby I can't go anywhere

Without thinking that you're there

Seems like you're everywhere, it's true

Gotta be having dejа vu

'Cause in my mind I want you here

Get on the next plane, I don't care

Is it because I'm missing you,

That I'm having dejа vu?

Boy, I try to catch myself but I'm out of control

Your sexiness is so appealing I can't let it go!

Whoooaaaaaahhh!

You know that I can't get over you

'Cause everything I see is you

And I don't want no substitute

Baby I swear it's dejа vu

You know that I can't get over you

'Cause everything I see is you

And I don't want no substitute

Baby I swear it's... dejа... vu

You know that I can't get over you

'Cause everything I see is you

And I don't want no substitute

Baby I swear it's dejа vu

You know that I can't get over you

'Cause everything I see is you

And I don't want no substitute

Baby I swear it's... dejа... vu

《Déjà Vu》仿佛暗喻前作《Crazy in Love》和迈克尔·杰克逊的《Off the Wall》。在音乐结构上，《Déjà Vu》以G小调为关键，内部被设有约每分钟106次的节拍乐器。作为录唱歌手，碧昂丝·吉赛尔·诺斯的音域从D♯4横跨至F5，她的引吭高歌如丝般光滑，且从容自若，与该曲的低音配置对比鲜明，堪比蒂娜·特纳正值风华正茂时的大家风范。

《Déjà Vu》的音乐视频于2006年6月21日拍摄，由英国导演苏菲·穆勒执导，拍摄地点位于新奥尔良。在音乐视频中，碧昂丝·吉赛尔·诺斯一人身穿五花八门的服饰分别在黯淡无光的房屋、郁郁葱葱的丛林、生意盎然的草地、波光粼粼的小溪歇斯底里地舞蹈。当说唱桥段响起时，碧昂丝·吉赛尔·诺斯放浪地挑逗Jay Z，而Jay Z却若无其事、洁身自好。其中，碧昂丝·吉赛尔·诺斯带性暗示的举措产生了负面影响。
