1. separate or distance yourself from someone/something
disassociate yourself from someone/wrong doing/a project
When you disassociate yourself from something, it usually means to distance yourself from something you disagree with or have an issue with. When you disassociate yourself you want to make a clear boundary between you and an ideology, ethos, project or scheme of work: "Although we have worked with Marcus in the past we would now like to disassociate ourselves from that work and his current right-wing ideology." "If you decide to work in this way I am afraid I will have to disassociate myself from the project, I can't stand behind it." "We would ask that all of our suppliers disassociate themselves from any practices involving child labour." This is an expression usually used in formal addresses or public statements.
