Redfield College is an independent Roman Catholic all-boys early learning, primary, and secondary day school, located in Dural, a suburb in the Hills District of Sydney, New South Wales, Australia.

The college was founded in 1986 by the Parents for Education Foundation and provides an education for students from early learning, through Year 2 to Year 12.

Each student is allocated a personal mentor, formerly known as a "tutor" within the school, who meets the student regularly (ideally fortnightly) to check on the student's advancement academically, socially, spiritually, etc. The mentor tends to guide the same student over a period of years, and meets with the parents of the student each term. This system is the same across all the Schools of The PARED Foundation.

Redfield College is an independent school. The Chaplains at the college are priests of Opus Dei, a personal prelature of the Catholic Church. Redfield offers daily mass and the Sacrament of Reconciliation to students, parents and teachers as well as other faith-based practises of the Catholic Church. The current chaplains at the college are Fr Phil Elias (Class of 2000) and Fr Frank Garcia.

As of 2023, there have been 11 Redfield Old Boys ordained to the priesthood, including Diocesan, Franciscan, Dominican and Opus Dei priests.

Although founded in 1986, Redfield's first HSC class was the Class of 1993. Since then Redfield has undertaken the HSC every year and 2022 marked its 30th HSC cohort. Although the school has a relatively small cohort compared to other schools in NSW, the College has consistently ranked within the top 150 schools for the last 20 years. In 2023, the NSW ranking for Redfield College is #43 with HSC results

Throughout their schooling lives, Redfield students complete many Community Service Projects, both locally and abroad. In Year 9, boys do a small project that they complete weekly over a year. These include visiting disabled students, nursing homes, and community gardening. At the end of Year 10, students attend a five-day camp, known as "Work Camp", wherein they travel to the Riverina town of Darlington Point to work on farms and in the homes of elderly couples. In Years 10–12, many Redfield students attend the annual "Vietnam Workcamp", wherein they travel to K'Long Village, near Dalat, Vietnam, to built homes for impoverished families.

Redfield has frequently hosted visits from, and sent students to, Mikawadai College in Nagasaki, Japan, and three schools in Spain: Colegio Viaro in Barcelona, Colegio Gaztelueta in Bilbao and Colegio Los Robles in Oviedo. In recent years boys from Monte VI in Montevideo, Uruguay and Colegio Penalba in Valladolid have also visited each year as well as a class of students from Tak Sun College in Hong Kong. Boys are billeted with families.

Redfield's principal sports include football, rugby union, basketball and cricket. Redfield's sporting division is affiliated with the IPSHA (Independent Primary School Heads of Australia), ISA (Independent Sporting Association), and CIS (Combined Independent Schools). Redfield's senior Rugby team (the 1st VX) has won the ISA second division championship six times since joining the ISA in 2006, more than any other school in the Independent Schools Association.

The Redfield First XI won the Second Division Football Championship in its inaugural year in 2012, and won the 2014 and 2015 seasons comprehensively. More recently they won the 2016 and 2017 season.
