The Connect Charter School, formerly the Calgary Science School, is a Canadian public charter school in Calgary, Alberta; which teaches grades four through nine.

The school was established in 1998 as Calgary Science School and moved to its current location, formerly the Calgary Board of Education's Clem Gardner Elementary School, in 2002.

The school originally conducted placement testing to ensure average academic performance in students admitted to the school, but this is no longer the case. Students can enroll and be granted a spot in the school solely after being selected from the top of the wait list and paying annual enrichment fees, regardless of their academic performance or needs.

In July 2012, the school was granted a 15-year charter from the Alberta Government. The school was renamed to the Connect Charter School effective January 1, 2014.

At the time of writing, there are 104 students each in grades 4–9. Wait lists are held for each grade in the event of students leaving or transferring away.

Ten buses, owned and operated by Southland Bussing of Calgary service CCS, taking the majority of the kids to and from school every school day.

Currently, CCS has over 50 staff members, including janitorial staff, technical staff, office attendants, and those in charge of publications.

CCS maintains a 1-to-1 student to computer ratio, and it finished the transition from a Windows to a Mac base in the beginning of the 2006–2007 school year. Due to an Emerging Technologies grant from Alberta Education, in the 2006–2007 and 2007–2008 school years, each student received their own Apple MacBook. Students continue to be provided an iPad as part of their enrichment fees and the school's efforts to integrate technology into what it calls "inquiry-based learning".
