**Abstract**

Despite its benefit and aged long practice, contraceptive use continues to be a problem in low and middle-income countries like Nigeria with one of the highest maternal and child mortality across the globe. This chapter aims to discuss social and behavior change interventions needed to scale up contraceptive use in low and middle-income countries. A review of literature in addition to field experiences in promoting contraceptives was made. Evidence reveals that a well plan and carefully implemented social and behavior change intervention based on formative research is key to improved contraceptive use needed for improved maternal and child health outcomes in low and middle-income countries. Contraception is the right of every woman and a recommended practice for the health and development of any nation.
