Arcane (titled onscreen as Arcane: League of Legends) is an adult animated steampunk action-adventure television series created by Christian Linke and Alex Yee. It was produced by the French animation studio Fortiche under the supervision of Riot Games, and distributed by Netflix. Set in Riot's League of Legends universe, it primarily focuses on sisters Vi and Powder. The series was announced at the League of Legends tenth anniversary celebration in 2019, and its first season was released between November 6 and 20, 2021. A second and final season was released between November 9 and 23, 2024.

The first season was met with universal acclaim, with praise directed at its animation, story, worldbuilding, action sequences, characters, emotional weight, sound, and voice acting. The second season also received highly positive reviews, with praise for the animation, visuals, and vocal performances, while its pacing had a mixed response. Some have noted the series' appeal both to viewers who have never played League of Legends and to long-time fans of the game. It also set the record as Netflix's highest-rated series at the time within a week of its premiere, ranked first on the Netflix Top 10 Chart in 52 countries, and ranked second on the chart in the United States. Several critics and publications considered it one of the best video game adaptations ever made. In 2022, the series became the first streaming series to win a Primetime Emmy Award for Outstanding Animated Program and won an Annie Award for Best General Audience Animated Television Broadcast Production.
