Leisure activities enjoyed by older married couples play an important part in creating more meaningful married lives. The study focuses on the prevalence of joint leisure activities by older couples, the factors influencing older adults' engagement in leisure activities together, and the relationship between joint participation in leisure activities and marital satisfaction of older couples. The quantitative sample included 414 married respondents aged 55 years and above from different parts of Vietnam. The leisure activities analyzed in the paper include vacation/travel, watching movies, music, karaoke singing outside the house, walking around the house, attending cultural events and festivals, watching TV, drinking tea, and doing exercise. The study results showed that the level of joint engagement in leisure activities in places near home with less cost was higher than those engaged in elsewhere. Couples with better living standards, higher education, better health, and who lived in urban areas more actively participated in leisure activities far from home. Vietnamese couples who engage in more leisure activities together had a higher level of overall satisfaction with their marriage, and greater satisfaction in several dimensions of their marital relationship than those who did not participate in leisure activities with their partners.
