The United States lags behind other industrialized countries in its lack of inclusive parental leave policy after the birth or adoption of a child. Using data from the Fragile Families and Child Wellbeing Study (N = 2,233), this study examines the patterns and predictors of fathers’ parental leave use, as well as its association with father–child engagement. Our findings indicate that the vast majority of employed fathers take parental leave, but they rarely take more than one week of leave. Fathers who have more positive attitudes about fatherhood and who live with the birth mothers are especially likely to take leave, and to take more weeks of leave, than other fathers. Finally, we find that taking parental leave, and taking more weeks of parental leave, is positively associated with fathers’ engagement levels at one year and five years after the birth of their children.
