Nobody's Boy: Remi (Japanese: 家なき子, Hepburn: Ie Naki Ko, lit. 'Homeless Child') is a 1977–1978 Japanese anime series by Tokyo Movie Shinsha and Madhouse. The story is based upon French author Hector Malot's 1878 novel Sans Famille. It follows a young boy who works for a travelling group of players in the hope of earning money and seeing his foster family again. The anime is well known in Hong Kong, Taiwan, Latin America, especially Mexico, Canada (in French), France, the Netherlands, Italy, the Arab world, Indonesia, Russia and the Philippines.

A film version by the same studio and director was released in 1980.

In the Philippines, the anime was originally shown between 1979 and 1980 on RPN, but like the other contemporary anime broadcast in the same period (Candy Candy, Heidi, etc.), the full story was not shown. It was only after nearly twenty years that it was shown in full, under the title Remi on ABS-CBN, this time in Tagalog. ImaginAsian attempted to make the show available in America through on-demand DVD, but with no success. AnimEigo has licensed the show and will release it on Blu-ray in 2025.

In Mexico, the entire series was shown several times in the 1980s, with several generations experiencing and knowing the story as part of their upbringing. The same happened with Candy Candy and Heidi in that Latin American country, although Remi is possible the best known, as it was shown by the dominant TV station of the time, at the daily afternoon cartoon segment, between 4 and 7 pm, which was one of the 1980s traditions that all Mexican kids knew and enjoyed.

In the Netherlands, it was broadcast between 1979 and 1980 by AVRO and in 1996 by the EO. The AVRO version was released on DVD.

In 1996, a new adaptation of this story was aired in Japan. Remi, Nobody's Girl (家なき子レミ, Ie Naki Ko Remi) was created by Nippon Animation as part of their World Masterpiece Theater series.

In 1995, Nobody's Boy: Remi was also broadcast by RCTI.
