Research on family strength is growing. Limited work has been studied about family strength during the COVID-19 pandemic in Indonesia. This qualitative online survey studied on 65 participants, aged 27–57 years (M = 40.85, SD = 6.8), to explore the characters of Indonesian family strength during the COVID-19 pandemic. Qualitative data were analyzed thematically. This research discovered eight characters of Indonesian family strength, namely:(1) intense and open communication, (2) intimacy and time together, (3) cooperation and division of roles, (4) finding solutions to problems, (5) implementing health protocols, (6) financial stability, (7) religiosity/spiritual well-being, and (8) grateful and optimistic. These eight characters coupled with two other areas, (9) self-development, and (10) concern for the needs of others, become 10 areas that growing up in families during the pandemic. These findings highlight the importance of focusing on characters of family strength when facing crises and uncertainties.
