In computer programming, a dope vector is a data structure used to hold information about an array, especially its memory layout.

A dope vector typically contains information about the type of array element, rank of an array, the extents of an array, and the stride of an array as well as a pointer to block in memory containing the array elements.

It is often used in compilers to pass entire arrays between procedures in a high level language like Fortran.
