Is it you and me or you and I?

It can be you and me or you and I depending on the sentence. “You and I” is correct for a sentence subject because it’s in the nominative case (e.g., “You and I should have lunch”). 

 

“You and me” is correct when you need the accusative case for a direct object or the dative case for an indirect object or object of a preposition (e.g., “The restaurant reserved a special table just for you and me”). 

 

Use the subject pronoun “I” for nominative case and the object pronoun “me” for the accusative/dative case (aka the objective case).
