This study sought to understand the link between trait mindfulness, forgiveness, and relationship satisfaction. Previous research established a significant positive relationship between mindfulness and relationship satisfaction, but forgiveness had not been studied in relation to these variables. Two hundred and nineteen couples in committed romantic relationships were included in the sample and completed self‐report measures on trait mindfulness, forgiveness, and relationship satisfaction. Upon conducting an actor–partner interdependence model mediation (APIMeM; Zeitschrift für Sozialpsychologie, 2006, 37, 27–40) analysis for dyadic data, results indicated significant positive associations for both inter and intrapersonal effects for both men and women. Findings indicated forgiveness is linked to both individual and partner mindfulness and relationship satisfaction, such that a person’s ability to be mindful can impact the ability to forgive and therefore increase relationship satisfaction.
