South Africa will play England in three matches over the space of six days from February 4 and will be led by wicketkeeper-batsman De Kock.
Du Plessis, under mounting pressure as the Proteas' Test leader, has recently discussed which international commitments he will keep after this year's T20 World Cup and he is not in the 15-man squad for the series.
Cricket South Africa, while not directly naming the previous ODI skipper, indicated in Tuesday's announcement that some senior members of the squad have been rested as they look to blood young players. Along with Du Plessis, Kagiso Rabada, Dale Steyn and Chris Morris have all been omitted.
De Kock has 115 caps and 4,907 runs in the 50-over format, while du Plessis is the country's highest-ranked batsman and fourth in the ICC ODI rankings.
"We all know the quality of the player that Quinton de Kock has grown to become," said Graeme Smith, the CSA acting director of cricket.
"Over the years, we have watched him grow in confidence and become one of the top ODI wicketkeeper-batsmen in the world. He has a unique outlook and manner in which he goes about his business and is tactically very street smart.
"We are confident that the new leadership role will bring out the best in him as a cricketer and that he can take the team forward into the future and produce results that South Africans the world over can be very proud of.
"We wish him the very best in this new role and look forward to watching him make his mark in this series against the World Cup champions."

South Africa begin to build for the 2023 World Cup with a squad that includes five first-time call-ups in Lutho Sipamla, Sisanda Magala, Bjorn Fortuin, Janneman Malan and Kyle Verreynne.
After England's win over South Africa in the third Test of the ongoing four-match series at St George's Park, Du Plessis had outlined there were likely changes to his commitments ahead, also suggesting he may opt to give up Test cricket.
Du Plessis said: "There isn't a lot of Test cricket left this year. There's one massive Test where we need everyone to be as strong as possible to try and draw the series.
"After that, there is quite a big gap and there is an opportunity then to release some of the captaincy when it comes to giving guys opportunities especially in one-day cricket.
"If I am brutally honest with myself, at the moment white-ball cricket is where I am most successful.
"In one-day cricket, my stats are up there with the best in the world. In T20 cricket, my stats are up there, but at the moment in Test cricket, my stats are not where they need to be."
South Africa ODI squad to face England: Quinton de Kock (captain), Temba Bavuma, Bjorn Fortuin, Beuran Hendricks, Reeza Hendricks, Sisanda Magala, Janneman Malan, David Miller, Lungi Ngidi, Andile Phehlukwayo, Lutho Sipamla, Tabraiz Shamsi, JJ Smuts, Rassie van der Dussen, Kyle Verreynne.
