Ariadna Thalía Sodi Miranda (Spanish pronunciation: [aˈɾjaðna taˈli.a ˈsoði miˈɾanda]; born 26 August 1971), known mononymously as Thalía, is a Mexican singer, songwriter and actress. Referred to as the "Queen of Latin Pop", she is considered one of the most successful and influential Mexican artists. Having sold around 25 million records worldwide, she is one of the best-selling Latin music artists of all time. Aside from her native Spanish, Thalía has also sung in English, French, Portuguese and Tagalog.

Her accolades include five Billboard Latin Music Awards, eight Lo Nuestro Awards, seven Latin Grammy Award nominations, and the Latin Recording Academy's President's Merit Award in 2019. She has collaborated with multiple artists, such as Tony Bennett, Michael Bublé, Robbie Williams, Marc Anthony, Laura Pausini, Romeo Santos, Maluma, Fat Joe, and Carlos Vives.

As an actress, Thalía starred in a variety of successful telenovelas that aired in over 180 countries with an estimated audience of 2 billion people according to UNICEF, which led to her being called the "Queen of Telenovelas". The global impact of her telenovelas helped her popularize her music in non-Spanish speaking territories and markets in Europe and Asia. The Mexican media company Televisa called her the best-paid telenovela actress in history, while Billboard said she is the most widely recognized Spanish-speaking soap star in the world.

Considered a Latin pop icon, Thalía was included among Billboard's Greatest Latin Artists of All Time in 2020 and People En Español's 100 most iconic Hispanic entertainers of all time in 2008. On 5 December 2013, she was honored with a star on the Hollywood Walk of Fame in recognition of her achievements in the music industry. As a businesswoman, Thalía enjoyed success with a fashion brand (having signed a deal with Macy's), as well she had her own nationally syndicated radio show and is the author of four books, including her memoir. During her career, Thalía has been involved in humanitarian causes and is a UNICEF Mexico Ambassador since 2016.

Ariadna Thalía Sodi Miranda was born on 26 August 1971 in Mexico City. She is the youngest of five daughters of Yolanda Miranda Mange (d. 2011), a painter who was Thalía's manager from 1980 to 1999 and Ernesto Sodi Pallares (d. 1977), a scientist, doctor of pathology, criminologist and writer. Her father's paternal grandfather, who was born in Florence, Italy, emigrated to Mexico during the Italian diaspora. Her four sisters are Laura Zapata (daughter of Guillermo Zapata Pérez de Utrera), Federica, Gabriela and Ernestina Sodi.^{[citation needed]}

When she turned one, Thalía appeared in her first TV commercial in Mexico. At the age of four, she began taking ballet and piano classes at the Conservatorio Nacional de Música (Mexico). Her father suffered from diabetes and died in 1977 when Thalía was six years old.^{[citation needed]}

Years later, Thalía admitted publicly that her father's death had traumatized her drastically, since she had lost her voice for a whole year. This led to her being diagnosed with childhood disintegrative disorder (CDH), which belongs to a series of developmental disorders related to autism spectrum. She has said that she had psychological therapy for few years. She has reportedly mentioned that she was a victim of bullying as a child because of the loss of her father.

Thalía attended Lycée Franco-Mexicain elementary school, where she learned to speak French fluently at a very young age. In 1976, a year before her father's death, she had a guest appearance in the Mexican film La guerra de los pasteles  [es] ("War of Cakes"), although her name doesn't appear in the film credits.
