The Purple Comet! Math Meet is a free, annual, international, online, team, mathematics competition designed for middle and high school students that has been held every year since 2003. Teams of from one to six students compete by submitting solutions to a list of mathematics problems. Each year there is a ten-day window during which teams may compete by choosing a start time most convenient for them. The problems range in difficulty from fairly easy to extremely challenging. In 2025 over 12,000 students participated on over 4000 teams from 80 countries.

There are two levels of competition:

• the middle school contest consists of 20 problems to be completed in 60 minutes;
• the high school contest consists of 30 problems to be completed in 90 minutes.

There are four categories of teams:

• teams whose members all attend the same large school;
• teams whose members all attend the same small school;
• teams whose members attend more than one school or are homeschooled;
• teams with no restrictions that do not compete for awards.
