"María La Del Barrio" is a song by Thalía, released as the third single from her fourth album En Éxtasis and also as the theme song from the telenovela of the same name. "Maria La Del Barrio" followed the "Thalia mania" success around the world and was a number one single in more than 20 countries. The song is considered one of her signature songs and was a smash hit.

"Maria La Del Barrío" was first released with an edited version as the opening and main theme of the soap opera of the same name in July, 1995. With the success of Thalia's previous singles, "Piel Morena" and "Amándote", it was chosen to be the third single from her fourth album, En Éxtasis.

Originally released as a single and in the original entire version in 1995, "María La Del Barrio" became a snapshot hit. The popularity of the song was as big as Piel Morena and even bigger in some countries. Thalia promoted the song in several TV shows, events, awards and concerts.

With the increasing success of the soap opera, the single also became more popular and achieved a heavy airplay and multiple certifications around the world. It is considered one of Thalía's classic.

In 1995 "María La Del Barrio" was a very popular song in Central and South America before its original release. With the transmission of the soap opera in over 180 countries, the song was officially released as a single and became a success in several countries.

As Thalia's previous soap operas theme singles - "María Mercedes" and "Marimar" - "María La Del Barrio" was one of her most popular songs in countries without a strong Spanish-language phonographic market. It was a number one single in more than 20 countries.

With the phenomenal success in the Philippines, where it was the most played song in 1997, Thalia recorded the song in Tagalog version, with the title "Mariang Taga-Barrio". It was a part of her Philippine album "Nandito Ako".

The official music video for the song was broadcast on TV a few times and today is considered a rare material in her career. Directed by Beatriz Sheridan, the video consists of a footage as seen in the opening of the soap opera, but without credits and using the entire song, with extra and exclusive scenes.
