The Mercedes-Benz R107 and C107 are sports cars which were produced by Mercedes-Benz from 1971 until 1989, being the second longest single series ever produced by the automaker after the G-Class. They were sold under the SL (R107) and SLC (C107) model names in a variety of names indicating the displacement of the engines.

The R107/SL was a two-seat convertible with a detachable roof. It replaced the W113SL-Class in 1971 and was replaced by the R129 SL-Class in 1989.

The predecessor W113 was notably successful in North America, with 19,440 units (40%) of 48,912 total units sold in the US.[2] The R107 and C107 were even more focused on the American market, with specialized engines, bumper designs, headlights, and emissions management designs. The R107 and C107 sold 204,373 units in the US (68%) of 300,175 total units sold (excluding grey market sales into the US).
