The RD801 (Ukrainian: {{lang|uk|РД801}}) is a Ukrainian liquid propellant rocket engine burning LOX and Kerosene (RG-1) in a staged combustion cycle. It has a single combustion chamber that provides thrust vector control by gimbaling of the nozzle in two axis by +/- 6°. It is being designed in Ukraine by Yuzhnoye Design Bureau for the prospective first stage propulsion of the Mayak rocket family.
The RD801 as well as the RD-810 are being designed based on the work of the RD-8 vernier and the maintenance and improvement of the RD-120 engines. The RD801 can be used stand alone on a Mayak or in a cluster.
Versions
The designers have proposed three versions of this engine:

- Mayak – Prospective Ukrainian launch vehicle family for which the RD801 is being developed.
- RD-8 – The Zenit second stage vernier engine which was the technological base for the RD801.
- RD-120 – The Zenit second stage main engine which was the technological base for the RD801
- RD-810 – A higher thrust engine of the same family.
- Yuzhnoe Design Bureau – The RD810 designer bureau.
- Yuzhmash – A multi-product machine-building company that's closely related to Yuzhnoe and would manufacture the RD801.
- YF-100 – A Chinese rocket engine of similar specifications based on RD801 design.
