He will be responsible for products including WSJ.com, SmartMoney.com and MarketWatch, as well as other language versions of the WSJ site.
According to a release from Dow Jones, Narisetti's appointment will be a return to the company, as he first worked at the WSJ as a reporter in 1994.
He rose through the ranks to the roles of editor of the Europe edition as well as deputy national news editor and deputy managing editor. Narisetti will join WSJ next month to fill the role vacated by former managing editor of WSJ.com Kevin Delaney.
In a statement, Robert Thomson, editor-in-chief of Dow Jones and managing editor of the WSJ, said: "Raju has done remarkable work as the digital tsar at the Washington Post, integrating print and online businesses, building a successful web site, and developing key relationships with the digerati.
"His experience in creating Mint, a national web site and newspaper in India, also brings important relationships and unique expertise that will assist us as we expand our global digital network. Raju is wired, and we are jazzed."
