This study aimed to identify the convergence relationships among nutrition knowledge, health beliefs, diet self-efficacy, and diet management behaviors among Sri Lankans with hypertension (HTN). 91 adults diagnosed with HTN for more than one year participated in this study. A set of interviewer-administered questionnaire was used to assess general characteristics, nutrition knowledge, health beliefs, diet self-efficacy, and diet management behaviors. A stepwise multiple regression analysis was conducted to identify the factors that might influence diet management behaviors. There were statistically significant positive correlations between nutrition knowledge (r=0.26, p=.013), health beliefs (r=0.35, p=.001), diet self-efficacy (r=0.34, p=.001) and HTN diet management behaviors. Three variables, nutrition knowledge, health beliefs, and diet self-efficacy, explained 19.9% of the variance in HTN diet management behaviors (F=8.36, p=.001). Diet self-efficacy was the most significant influencing factor (${\beta}=.29$, t=2.75, p=.007), followed by nutrition knowledge (${\beta}=.25$, t=2.50, p=.014). The findings of this study can be used as valuable data for developing effective interventions to improve diet management behaviors of persons with HTN.
