An insurance policy that covers only one specific type of risk (insurance risk). Examples of a monoline insurance policy include life insurance, auto insurance, liability insurance, etc. Certain brokers and agents may consider clients in need of only one type of insurance policy as a monoline client.

Monoline or monoline insurance policy is opposite to a package policy (bundled insurance) that consists of a number of different coverage types, such as property insurance and liability insurance in the same policy. A package policy is usually less costlier than insurance coverage acquired separately or stand-alone.

For example, if a client seeks to acquire a package insurance policy, but the underwriter does not sell liability insurance – the client would need to purchase a monoline products liability policy.

A monoline insurance policy is also called a stand-alone insurance policy.
