Tim Cahill, Jack Rodwell and Seamus Coleman has signed new deals earlier this deal.
Baines has signed a new five-year contract with Everton.
He told the club’s official website: “I’m more than happy to be staying here and committing to the club and it was nice for the club to want me to stay.
“It was simple – it would have been done quicker if I hadn’t been away on holiday.
“I still had two years left so wasn’t really thinking about it but the manager said to me at the end of last season that I had done well and he wanted to reward me with a new contract, which was great.
“It is nice to have it sorted before we go away to Australia because I can focus on the football and not have anything going on in the background.
“I’m fully-focussed on the trip to Australia and hopefully that will be a good trip leading to a good season.”
