The Proterra ZX5 is a battery-electric transit bus available for sale in the United States and Canada. Available in 35ft and 40ft lengths, it is the company's fifth generation of battery electric bus. The ZX5 was formally launched on September 15, 2020, replacing the Catalyst line of buses. Edmonton Transit System was the launch customer for the 40-foot ZX5. The Southern Teton Area Rapid Transit was the launch customer for the 40-foot ZX5 in the United States.

The ZX5 features the same fibreglass and balsa wood body structure as the Catalyst, but incorporate design changes to both increase battery capacity and standardization with electric vehicle charging protocols. The overall appearance of the vehicle has been made more angular, while the roof fairing has been made more streamlined with provisions for roof-mounted battery packs, as well as integrated SAE J3105 (OppCharge) roof charger rails. The redesigned roof fairing has also resulted in an overall decrease of the vehicle's height by 6 inches. An additional plug-in charge port has also been added ahead of the front doors. The suspension system of the vehicle has also seen improvements. The drivetrain options have been updated with slightly more powerful motor offerings.

The standard ZX5 model, with a 220 kWh energy storage system (corresponding to the previous Catalyst XR model), can travel up to 201 km (35ft) or 193 km (40ft) on a single charge, depending on the configuration of the vehicle. The ZX5+ model with a 440 kWh ESS (corresponding to the Catalyst E2 model) can travel up to 386 km (35ft) or 373 km (40ft) on a single charge. The ZX5MAX is the longest-range option available. With a 660 kWh energy storage system, the ZX5MAX can travel up to 529 km on a single charge. The ZX5MAX battery option is only available for the 40-foot length ZX5.

The ZX5 can be charged using the SAE J3105 (OppCharge) overhead pantograph charging protocol, or with a J1772 CCS charger in the depot. The ZX5 with any battery option can be fully charged in around 2.9 hours using the OppCharge overhead charging system. Utilizing plug-in charging, the standard ZX5 takes around 2.9 hours to be fully charged, while the ZX5MAX takes around 4.7 hours to be fully charged.
