J.C.Staff produced two 24-episode anime series between 2008 and 2011. An animated film was released in February 2013. The anime adaptations are licensed in North America by Funimation.

A Certain Magical Index is set in a world where supernatural abilities are a reality. Individuals who possess special powers acquired via science are called Espers (超能力者 Chōnōryokusha). Those Espers who gain their abilities without the aid of special scientific instruments, whether at birth or otherwise, are referred to as Gemstones (原石 Genseki). Others, known as Magicians (魔術師 Majutsushi), gain their powers upon mastering the power of magic, either from obtaining knowledge from different mythologies or by using mystical artifacts, though the existence of magicians is a secret to the public. While Magicians align themselves with different beliefs, Espers are aligned with scientific institutions. This leads to a power struggle between the magic and science factions for control of the world.
The story is set in Academy City (学園都市 Gakuen Toshi), a technologically advanced city located in west of Tokyo that is known for its educational and research institutions. Tōma Kamijō is a student in Academy City whose right hand, the Imagine Breaker, has the ability to negate any supernatural power, but also negates his own luck, much to his chagrin. One day, Tōma meets a young English girl named Index – a nun from Necessarius, a secret magic branch of the Church of England, whose mind has been implanted with the Index Librorum Prohibitorum – 103,000 forbidden magical books that the Church has stored in secret locations. His encounter with her leads him to meet others from the secret worlds of science and magic. Tōma's unusual power places him at the center of conflicts between the Magicians and Espers in Academy City who try to unravel the secrets behind Academy City, Index, and Tōma's own special power.
Besides its own manga adaptation, the series also has two manga series which are side stories focusing on other main characters. One of them is A Certain Scientific Railgun, which focuses on Mikoto Misaka, an Electromaster and one of the most powerful Espers in the city. The second, A Certain Scientific Accelerator, focuses on Accelerator, a teenager who can control vectors, known as the most powerful Esper in Academy City.
