The New Jersey Department of Health says the child is under 5 years old and was from the northern part of the state, and had no underlying health problems.
Health officials also say this is a stark reminder that parents should have their children vaccinated, especially toddlers and younger.
"This flu season is already shaping up to be a very serious one, with more cases than previous years and, tragically, one child's death this week. We extend our deepest condolences to the child's family," said Acting Health Commissioner Jeff Brown. "By getting vaccinated, we can each do our part in reducing the spread of flu and other respiratory viruses in New Jersey and helping prevent serious complications."
Medical experts blame a drop in vaccinations as a big reason for the country's largest flu outbreak in 25 years.
They say the vaccination remains the most effective protection against the transmission of the flu, and while it is recommended to get it earlier in the season, they say it's not too late to get the shot.
