This is a list of mutual-fund families. A family of mutual funds is a group of funds that are marketed under the same (or similar) brand names, usually having the same distributor (the company which handles selling and redeeming shares of the fund in transactions with investors), and frequently having the same investment advisor (which is usually a corporate cousin of the distributor). Multiple funds in a family can be part of the same corporate structure; that is, one underlying corporation or business trust may divide itself into more than one fund, each of which issues shares separately.

There are hundreds of families and thousands of individual mutual funds, too many to list here; see the fund family's Web site or one of the third-party resources mentioned in the mutual funds article for more information.
