Nawalka replaced Waldemar Fornalik as Poland coach in 2013
Poland coach Adam Nawalka will step down at the end of July, following his team's early World Cup exit.
The 60-year-old's contract was due to expire after the tournament anyway and the Polish FA have decided not to extend it.
Poland lost their opening two Group H games and were the first European side to be knocked out in Russia.
"We will try to build a national team in a new way," said the Poland Football Association's Zbigniew Boniek.
- "We failed the fans and ourselves"
Nawalka, who won 34 caps as a player for his country, said he takes "full responsibility" for the team's failure at a joint news conference with Boniek.
"Of course I feel responsible that we did not meet expectations, we did not meet our plans, ambitions, our fans' expectations... that we disappointed."
A 1-0 win in their third and final group match against Japan was not enough for Poland to avoid finishing bottom.
