Two people in the county won £25,000 and 12 scooped £10,000, while bondholders from Sefton and Sheffield got the top £1m prize this month.
Jill Waters, NS&I retail director, said: “Premium Bonds are a fun way to start saving - customers are in with the chance of winning any one of our more than 4.9 million prizes.
"People up and down the country can start their Premium Bonds journey with an initial investment of just £25.”
In the November draw, one person from Norfolk won a £100,000 prize.
Premium Bonds is an investment product issued by National Savings & Investments.
Unlike other investments, where investors earn interest or a regular dividend income, bonds are entered into a monthly prize draw where people can win between £25 and £1m tax-free.
Premium Bonds are available by investing at least £25.
