莫敬寬（，？ - 1638年）是越南莫朝第九代君主。1621年至1638年在位。莫敬恭侄孫和威王莫敬用之子。

原為莫朝的慶王。1594年，莫朝皇帝莫敬恭為鄭松所敗，出奔思明府，向明朝稱臣。莫敬寬率部據守太原與伯父莫敬恭會合。

1621年，莫敬恭讓位於其侄慶王莫敬寬，後者在大慈縣即位稱帝，更元隆泰，尊莫敬恭為太上皇。

1623年，鄭松逝世，其子鄭梉、鄭椿爭奪主位。莫敬寬趁機率軍南伐，並煽動各路勢力起兵叛亂。兵至嘉林縣，八月被鄭梉擊敗，莫軍全軍覆沒。莫敬寬僅以身免，遁入山林之中，逃回高平。1625年，鄭梉率兵攻陷高平，擒殺太上皇莫敬恭和莫朝皇太子等，莫敬寬與次子莫敬完遁入明朝。同年遣人向後黎朝上降表，去年號奉正朔。在明朝的壓力下，後黎朝封之為太尉、通國公，准許他回到高平。從此以後，莫朝的軍事實力更加衰弱，並且向後黎朝進貢。

1638年莫敬寬病逝，次子莫敬宇嗣位。
