Men in the district are likely to live almost three years longer than the national average, Public Health England (PHE) figures reveal.
Women's life expectancy rates in the area also sit a year above the national average, according to the latest data set.
PHE's 2015-2017 statistics show the average, healthy life expectancy of a man living in North Somerset is 66.2 years of age - 2.8 more than the average 63.4 figure across England.
The data set's figure is four months higher than the predicted 65.8 years, when a similar set of statistics were recorded between 2009-2011.
Meanwhile, women in North Somerset could expect to live 65.4 years in good health, figures from the same 2015-2017 data set show.
The rate has improved by around 20 months for women in the area since 2009-2011 figures were revealed.
Clinical chair at Bristol, North Somerset and South Gloucestershire CCG, Dr Jonathan Hayes, said: "The CCG's mission is to make health better for people living in North Somerset, Bristol and South Gloucestershire.
"The latest life expectancy figures from PHE are testament to the hard work of the CCG's health partners across the district, with its diverse and growing population, many of whom enjoy a fantastic quality of life.
"We are dedicated to reducing health inequalities and ensuring NHS services are fit for the long-term."
The latest statistics show the lowest life expectancy rate for men is in Blackpool, 54.7 years, while in Rutland people could expect to live an average of 69.8 years of good health - 15 years longer.
Figures have been calculated by the Office for National Statistics, who looked at death rates in different areas of the country.
People could also take part in surveys where they self-reported their level of health.
A spokesman for the Government's Department of Health and Social Care said: "The Government's plan for the NHS will aim to reduce health inequalities, which will be backed by an extra £33.9billion a year into the service, by 2023-24.
"We want everyone to have five extra years of healthy, independent life by 2035, and we are committed to ensuring people get excellent healthcare in the UK."
