Emma (エマ, Ema) is a Japanese historical romance manga by Kaoru Mori. It was published by Enterbrain in the magazine Comic Beam and collected in ten tankōbon volumes. The series has been adapted as an anime television series, entitled Emma – A Victorian Romance (英國戀物語エマ, Eikoku Koi Monogatari Emma). The manga is licensed in English in North America by Yen Press and the anime is licensed in English by Nozomi Entertainment.

Set in Victorian London at the end of the 19th century, Emma is the story of a housemaid who falls in love with a member of the gentry. However, the man's father and young siblings disapprove of him associating with people of the lower classes.

Both the manga and anime versions of Emma are unique for being set in a setting seldom visited by either medium without some fantasy or speculative element. The author and illustrator of the manga, Kaoru Mori, is a self-professed Anglophile, and attempted to recreate 1895 London with meticulous detail. The manga has a cult following in Japan, even going as far as opening an Emma-inspired and themed maid café in Shinjuku. Its popularity has sparked an interest in English maid cosplay, even going as far as having the official Emma anime website selling Emma's "costume" for ¥45,000.

Written and illustrated by Kaoru Mori, Emma was serialized in Enterbrain's seinen manga magazine Comic Beam from the January 2002 to the May 2006 issues. Enterbrain collected its 52 chapters in seven tankōbon volumes, released from August 30, 2002, to May 25, 2006. From the third volume onward, Rico Murakami [ja] served as historical consultant to ensure the historical accuracy of the manga. Additional stories, known as Emma: Extra Stories (エマ 番外編, Ema Bangaihen), were published in Comic Beam from the September 2006 to the March 2008 issues. These chapters were collected in volumes 8–10, released from March 26, 2007, to April 25, 2008.

In North America, the manga was first licensed by CMX Comics, which released ten volumes from September 20, 2006, to December 8, 2009. In October 2014, Yen Press announced that they had licensed the manga, and released in five omnibus edition volumes from May 19, 2015, to August 23, 2016. In September 2018, Yen Press announced the digital release of the manga.

The novelisations are written by Saori Kumi, and based upon the original manga.

The manga was adapted into a TV anime series, entitled Emma – A Victorian Romance (英國戀物語エマ, Eikoku Koi Monogatari Emma), directed by Tsuneo Kobayashi, scripted by Mamiko Ikeda, and produced by Studio Pierrot and TBS. The first season of the anime series premiered between April 2 and June 18, 2005, across Japan on several UHF TV stations, BS-i and the CS TV network Animax, who have also later aired the series across its respective networks worldwide, including Hong Kong and Taiwan, also translating and dubbing the series into English for its English language networks in Southeast Asia and South Asia, and other regions.

The Japanese title of the anime is written using a couple of kanji from before the adoption of simplified characters after the end of World War II, which reflects the usage of kanji in the time period the story is set in. In modern Japanese 英國戀物語 (Eikoku Koi Monogatari, lit. English Lovestory or Lovestory in England) would be written as 英国恋物語, the characters for country and love being replaced by their modern variants. The series' official English title is Emma - A Victorian Romance.
