In computer science, hash trie can refer to:
Hash tree (persistent data structure), a trie used to map hash values to keysA space-efficient implementation of a sparse trie, in which the descendants of each node may be interleaved in memory. (The name is suggested by a similarity to a closed hash table.) A data structure which "combines features of hash tables and LC-tries (Least Compression tries) in order to perform efficient lookups and updates"
