Notre Dame College School is a Catholic high school in Welland, Ontario, Canada with classes ranging from Grade 9 to Grade 12. The school was founded by the Holy Cross Fathers, a group of Roman Catholic priests who also founded the University of Notre Dame. In the early years of the establishment, tuition was levied to students attending the school; however, the institution is now completely publicly funded. Notre Dame is currently the largest secondary school in the Niagara Region, with 1243 students. All NCDSB elementary schools in the Welland and Pelham areas are considered to be feeder schools to Notre Dame.

The cheerleading team is a multiple time national champion. The varsity girls' Lacrosse team won the OFSSA Championships in 2011, going undefeated in the prestigious tournament. The school Reach for the Top team is a provincial-level competitor, and the Mathletes team is the regional champion. The school also supports a wide range of sports teams, including soccer, football, lacrosse, hockey, track and field and swimming.

Notre Dame's senior boys' basketball team is regarded consistently as one of the best in the Niagara Region. The school was a founding member of the local Tribune Tournament, winning the tournament the majority of the years since 2000. The 2013 boys' basketball team had an exceptional season winning the SOSSA championship and competing at the OFSAA AAAA championship.

The school has recently undergone several new expansions, including the 2006 addition of a new wing, and the 2007 construction of a lobby and front office. Of the School Boards 1.8 million dollar expansion budget for 2007, 1 million was reserved for Notre Dame. The new expansions have resulted in the school abandoning a section of portables which it had previously been using. The school also had a science and technology wing added in 1994.

To start the 2023/2024 school year, renovations on the new turf football field (Lacavera Field) and track were completed and their newly renovated drama theatre, Bates Hall opened during mid November of the 2024/2025 school year.
