The period drama - penned by Bill Gallagher - is currently airing on Tuesday nights and will soon return for eight more episodes.
Set in the glamorous world of the first ever department store, The Paradise has attracted an average consolidated audience of 5.9m across its first five weeks.
Danny Cohen, Controller of BBC One, said: "The Paradise has been the biggest new drama series on British television so far this autumn, and it has been really interesting to experiment with period drama on BBC One beyond the traditional Sunday night slot.
"I'm delighted that the show will be returning for a second series, and can assure its loyal following that there are still some dramatic twists to come in the three episodes still to air this autumn."
Bill Gallagher added: "I'm very grateful that there's such a strong audience for The Paradise, and for the terrific support the BBC has given to the show to make that possible.
"It's such a great ensemble of actors and such a rich group of characters that it's an exciting prospect to have eight more episodes to make."
Adapted from the classic French novel by Emile Zola, The Paradise stars Sarah Lancashire, Emun Elliott, David Hayman, Elaine Cassidy, Matthew McNulty and Patrick Malahide.
Guest stars in the first series have included Olivia Hallinan (Lark Rise to Candleford) and Arthur Darvill (Doctor Who).
The first series of The Paradise will conclude on November 13 at 9pm on BBC One.
