The invention relates to a transportable ultra-stable high-fineness optical Fabry-Perot reference cavity, which is suitable for an ultra-stable laser, and is characterized in that the transportable ultra-stable high-fineness optical Fabry-Perot reference cavity comprises a cubic cavity structure, a supporting structure, a heat shielding structure and a vacuum chamber structure, the cubic cavity structure forms stable frequency reference in the laser system; the supporting structure fixes the cubic cavity structure and is stably connected with the transportable ultra-stable high-fineness optical Fabry-Perot reference cavity and other laser systems, and the cubic reference cavity and the supporting structure are connected in an eight-point supporting mode. According to the transportable ultra-stable high-fineness optical Fabry-Perot reference cavity disclosed by the invention, laser always enters the reference cavity at a fixed angle in a transporting process; the heat shielding structure is used for isolating
