Since your sister's husband's daughter is usually your sister's daughter, you are her aunt or uncle.
If the husband's daughter is from a prior marriage (before he married your sister) then the daughter is not related to you. However, if the daughter is young, her father may have her call you and treat you as an aunt or uncle.
