The 1966–67 NCAA College Division men's ice hockey season began in November 1966 and concluded in March of the following year.
This was the 3rd season of second-tier college ice hockey.
ECAC 2 added Boston State who was an NAIA school.
Normally the conference would be forbidden to add a non-NCAA school as a member but because there was no national tournament for College Division schools no penalty was imposed.
