The venture kicks-off this weekend (1 October) and will involve 47 Football League games up-and-down the country, from Middlesborough to Portsmouth.
The initiative has been launched to enhance the game's image as an occasion which can attract whole families, not just a largely male demographic.
The Family Football Festival will feature a mix of fancy dress competitions, face painting and other family-geared half-time entertainment.
Each of the clubs involved in the initiative will announce specific activities this Saturday.
The festival will be advertised on Absolute Radio while the Football League is also running Facebook activity.
Additionally, a partnership with Netmums, the online forum for mums, will involve mummy bloggers reviewing Family Football Festival games.
David Malkinson, head of marketing at The Football League, said: "The Football League and its member clubs have worked hard in recent seasons to ensure that the family experience at npower Football League matches is safe, enjoyable and good value for money.
"Our Family Excellence Award has helped clubs deliver an outstanding experience for families and we believe that League Football is a great option for family, providing quality together time."
