 Claret School of Quezon City (Filipino: Paaralang Claret ng Lungsod Quezon), also referred to by its acronym CSQC or colloquially as Claret, is a private Catholic basic education institution run by the Missionary Sons of the Immaculate Heart of Mary in Quezon City, Philippines. It was established by the Claretians in June 1967 and was named after its patron saint, St. Anthony Mary Claret, who founded the Claretians in 1849. The school also has a Child Study Center which allows girls up to the Kindergarten level.
 The Claretian fathers dreamt of building a school in the Philippines after they had started their missions in Zamboanga and Basilan. They needed a base to serve as the center for Claretian activities in the country.[citation needed]
 In the late 1960s, Fr. José Querexeta, CMF, former bishop of the Territorial Prelature of Isabela, acquired a 29,101 square meter lot in UP Village, Diliman, Quezon City. In 1967, the construction of the first two buildings of the school (Xifré and Clotet) were supervised by Fr. Miguel Mialet, CMF. Fr. Santiago González, CMF was the first school director and principal.
 Under Fr. Santiago's guidance, the school quickly grew to include the Intermediate Grade School Department in 1968 and the High School Department in 1972. In the 1970s the school upgraded the old covered court into a gymnasium, and the Immaculate Heart of Mary Parish church was built.[citation needed]
 In 1981, González was replaced by Fr. Julián Mateos, CMF; Fr. Jesús Vásquez, CMF; Fr. Emilio Pablo, CMF; Fr. Luis Fernández Rey, CMF; and Fr. Domingo Moraleda, CMF. From 1981 until 1995, supervision of the school was transferred to Dr. Enrique Coralejo, a lay director.
 The 1990 Luzon earthquake forced the school to make reinforcements to the main buildings. During the same decade, the Sala building was completed as the last of the five main buildings of the campus. The Vilaró and Fàbregas buildings were also built during the 1990s.[citation needed] From 1995 until 2000, Fr. Agapito Ferrero, CMF was the school director.
 In 2000, Fr. Felimon P. Libot, CMF became the first Claretian priest of Filipino descent to be assigned as school director. He was superseded by Fr. Salvador G. Agualada, CMF in 2006.
 In 2007, the school celebrated its 40th anniversary and the TLE building was completed.
 In the middle of SY 2008–2009, Fr. Domingo Moraleda, CMF, former school director, died in an accident in Mabalacat, Pampanga.
 On June 1, 2009, Fr. Eduardo C. Apungan, CMF took office as the school director. He was superseded in 2010 by Fr. Renato L. Manubag, CMF. In May 2013, Very Rev. Fr. Christian James L. Castro, CMF assumed directorship of the school. In 2016, Very Rev. Fr. Efrén Limpo, CMF assumed position as the 14th school director of Claret School of Quezon City. He was succeeded by Very Rev. Fr. Mauricio T. Ulep, the current school director.
