Star Butterfly is a magical princess from the dimension of Mewni. On her fourteenth birthday, she receives the family heirloom wand. However, after she accidentally sets fire to her castle, her parents decide that a safer option is to send her to Earth as a foreign exchange student. There, she befriends Marco Diaz and lives with his family while attending Echo Creek Academy. Star and Marco must deal with everyday school life, while protecting Star's wand from falling into the hands of Ludo, a villain from Mewni who commands an army of monsters.
In the third season, Star returns to Mewni after she discovers that magic is disappearing throughout the kingdom. When Star discovers that her family’s history is linked to the use of dark magic and may be responsible for the monster mayhem in Mewni, she must dig deep and confront Ludo to save Marco, her family, and the kingdom.
The fourth season follows Star and Marco as they continue their adventures in Mewni and explore new dimensions. However, as things change in the royal palace, Star soon learns that running the kingdom is far more complicated than she once thought.

Home video releases
While the show has not had any physical home video releases, Star vs. the Forces of Evil has been mostly avalible for purchase on digital platforms such as Amazon Prime. 
Despite not being present at launch, all 4 seasons of Star vs. the Forces of Evil were added to Disney+ on December 1, 2019, less than a month after the debut of the streaming service in the United States and Australia. The show was, however, part of the launch lineup for the Latin American, Japanese and first wave of the European versions of Disney+, but only the first two seasons are available in Europe. On October 1, 2020, seasons 3 and 4 were added to Disney+ in the UK, following the closure of Disney Channel and Disney XD in the UK.
Star vs. the Forces of Evil was very well received with both critics and audiences, with some calling it, at the time, the best Disney TV animated show since Gravity Falls. Many critics have praised the show for its originality, unique art style, and memorable characters as well as its rich and deep lore and its writing of the relationships between charcters, particulary between Star and Marco. The first few episodes of the show were a little criticized for its lack of focus but many agreed that the show got better as it went on.
However, reception towards the last few seasons, particularly the final episode, Cleaved, was much less positive, with many fans agreeing that the ending of the show felt extremely abrupt and unsatisfying due to lack of build up of any tension during these seasons towards the ending chosen for the show, and instead seeming to focus more on the romantic relationships between the teenage characters through out the last season, leading many to believe that a fifth season was originally planned, and was already in development, but ended up being rejected by Disney, and, as a likely consequence, most of its elements had to be either cut or reworked into Season 4.
One of the most discussed and praised elements from show, among fans, is the relationship between Star and Marco with many fans considering it the main focus of the show and pairing them romantically in a similar way to how Kim Possible fans paired Kim Possible and Ron Stoppable while the show was airing.
- The show was originally under the title name Star and the Forces of Evil.
- The show was originally scheduled to premiere in Fall 2014 before it was pushed back to January 2015.
- The show was originally going to be a Disney Channel original series, but it was announced in Fall 2014 that the show would be a Disney XD series. However, the series began airing in re-runs on Disney Channel in September 2016. It currently airs on that network as part of the Disney Channel Weekend Mornings programming block.
- Daron Nefcy's influences for Star vs. the Forces of Evil are primarily Japanese TV shows, such as Sailor Moon, Dragon Ball Z, Magic Knight Rayearth, Revolutionary Girl Utena, and Unico (which features a pink unicorn). Her Japanese influences mainly come from widely intense shows with female leads.
- Originally, Star Butterfly was going to be a fourth grader but the executives wanted the character to be a little bit older. While it was different than what Daron Nefcy wanted, it did allow the show to play around with concepts that fall more in line with the teenage audience of Disney XD.
- This is also likely what lead the show to have a higher focus on the lore of the Butterfly Family and the romantic relasionship between Star and Marco, as none of these concepts are refrenced in Daron Nefcy's earlier versions of the show.
- Daron Nefcy has expressed interest in a continuation in the form of a film adaptation or a spin-off series.
