The Arizona Bitcoin Reserve refers to the Bitcoin reserve system planned to be established in the state of Arizona, USA.

On April 28, 2025, local time, the Arizona legislature passed two key bills. The first bill—Senate Bill 1025 (SB1025)—amends existing regulations to allow for the establishment of a strategic Bitcoin reserve, passing with 31 votes in favor and 25 against. It authorizes the Arizona State Treasurer to allocate up to 10% of public funds to virtual currencies such as Bitcoin. The other bill, SB1373, passed with 37 votes in favor and 19 against, establishing a digital asset strategic reserve fund managed by the State Treasurer, funded by seized assets and legislative appropriations, allowing for up to 10% investment in digital assets such as Bitcoin each fiscal year, and permitting borrowing without increasing risk.

These two bills are now submitted to Governor Katie Hobbs for signature, and if signed, Arizona will become the first state in the United States to officially establish a Bitcoin reserve.
