Lampard has been out of the game since being sacked as Chelsea boss a little over a year ago.
The former England international will take charge for the first time on Saturday when Everton host Brentford in the fourth round of the FA Cup.
“It is a huge honour for me to represent and manage a club the size and tradition of Everton Football Club. I’m very hungry to get started,” said Lampard.
“I think Everton is a unique club in that you can really understand what the fans want to see. The first thing they want is fight and desire and that must always be our baseline.
“My first message to the players will be that we have to do this together. We’ll try to do our job and I know the fans will be there backing us.”
Lampard takes charge with Everton just four points above the relegation zone.
Fans protested over the past week outside Goodison Park at the running of the club from British-Iranian businessman Farhad Moshiri.
Moshiri has spent over half a billion pounds on transfers since his takeover in 2016, but much of that money has been wasted.
Lampard becomes the club’s seventh permanent manager in less than six years.
His former England teammate Wayne Rooney turned down the chance to have an interview for the job, while Portuguese coach Vitor Pereira was reportedly the favourite until a fan revolt against his appointment.
“I am really delighted that Frank has joined us,” said Moshiri.
“He has played at the very highest level of the game and has football in his blood. He impressed us all greatly during the thorough interview process and we’re all ready to give him all of our support as he looks to give the team an immediate boost.”
After the visit of Brentford, Lampard has a baptism of fire back in the Premier League, with a trip to Newcastle on February 8 that could have a huge bearing on who is relegated at the end of the season.
