The Honda RC100 (also known as Honda RC-F1 1.0X, chassis number RC1-203/1) was a prototype Formula One car built by engineers from Honda R&D Center, Tochigi, although not as an official project of Honda. The car was completed in 1993 and initially tested at Honda's Suzuka Circuit. Two more cars, known as RC101 (RC-F1 1.5X, chassis RC1B-101) and RC101B (RC-F1 2.0X, chassis RC2-001), were also built and tested before the project ended.

These cars should not be confused with the Honda RA099, which was an official Honda prototype intended for the 2000 season but also never ran.
