A Segregated Fund (Seg Fund) is a type of investment fund administered by Canadian insurance companies in the form of individual, variable life insurance contracts offering certain guarantees to the policyholder such as reimbursement of capital upon death. As required by law, these funds are fully segregated from the company's general investment funds, hence the eponym.

A segregated fund is an investment fund that combines the growth potential of a mutual fund with the security of a life insurance policy. Segregated funds are often referred to as "mutual funds with an insurance policy wrapper". Like mutual funds, segregated funds consist of a pool of investments in securities such as bonds, debentures, and stocks. The value of the segregated fund fluctuates according to the market value of the underlying securities.
