This Collider article ranks the 15 best fantasy television shows released over the past decade, a period in which streaming platforms have poured significant budgets into the genre following the success of earlier hits. The list weighs both critical quality and commercial success, and includes shows currently airing as well as completed series, reflecting how fantasy has become a reliably lucrative and popular category across networks.

Entries include Amazon Prime Video's "The Lord of the Rings: The Rings of Power" (2022–present), which divides Tolkien purists but has proven a major draw for casual viewers; Netflix's "The Witcher" (2019–present), praised for its strong first season but criticised for declining quality and a recast lead actor; and "Good Omens" (2019–2026), a comedy adaptation of the Terry Pratchett and Neil Gaiman novel praised for its wit despite only receiving two seasons.
