The 25 largest property/casualty independent agencies are listed in the table below. The list is an excerpt from an agency ranking published by Insurance Journal, an online insurance news magazine. Each year the magazine composes a list of the 100 largest property/casualty agencies based on total property/casualty revenue. The Top 25 list is derived from Insurance Journal's 2018 ranking (published in 2019).

Three agencies that appeared on previous Top 25 lists were acquired by other companies in 2018. They are the Crystal & Co, which was acquired by Alliant Insurance Services; Hays Companies, which was acquired by Brown & Brown; and Wortham Insurance, which was acquired by Marsh.

Hub International, Lockton, Alliant, and several other companies on the Top 25 Agencies list are also included in the list of the 15 largest insurance brokers. These companies appear on both lists because they act as insurance agencies in some situations and insurance brokerages in others.

An insurance agency acts as a representative of an insurance company while an insurance broker acts on behalf of insurance buyers.

Here is the list of the largest 25 insurance agencies in descending order. For each agency, the table shows the revenue earned in 2018 and some remarks about the company. Note that the numbers in the revenue column have been rounded off.
