98 Degrees (or 98°) is a Grammy-nominated American adult contemporary boy band consisting of four vocalists: brothers Nick and Drew Lachey, Justin Jeffre, and Jeff Timmons. The group was formed by Jeff Timmons in Los Angeles.

Unlike most boy bands, they formed independently and were later picked up by a record label, as opposed to being assembled by a label or a producer (e.g. O-Town). They have sold over 10 million records and achieved 8 Top 40 singles.
