The winger saw his side draw 0-0 against rivals Brighton at Selhurst Park tonight in the npower Championship play-off semi-final first leg.
"It's all I want to do," Zaha told Sky Sports 1 when asked how much Palace's promotion means to him.
"I've been here for so many years but bringing Palace up to the Premier League would be the best thing ever."
But Zaha knows a tough task awaits in Monday's second leg on the south coast.
"It's a hard place to win but we will do the best we can and see what happens," Zaha said.
"We did the best we can and we just have to go over there and try and win it."
