The PowerShot Pro1 is a digital camera made by Canon, announced in February 2004 and was discontinued first quarter of 2006. It uses a Sony-built 2/3 in (17 mm) 8.3 megapixel CCD image sensor, which gives a usable image size of approximately 8.0 megapixels. It was the most expensive fixed-lens camera sold by Canon at the time, and thus the top of the PowerShot range. It was the first fixed lens designated a Canon L series lens, a designation normally reserved for expensive EF-series SLR lenses.

It has a variable-angle two-inch, polycrystalline silicon, thin-film transistor, color liquid crystal display with approximately 235,000 pixels and a colour electronic viewfinder (EVF) with the same resolution. The lens has a 35 mm equivalent zoom range of 28 to 200 mm. The shutter has a maximum speed of 1/4,000 second. The camera's dimensions are 117.5 mm in width, 72 mm in height, and 90.3 mm in depth. Its mass is 545 g.

The PowerShot products are a line of consumer and prosumer grade digital cameras, launched by Canon in 1996. The PowerShot line has been successful for Canon, and is one of the best-selling digital camera lines worldwide.

Free software from the Canon Hack Development Kit (CHDK) project allows nearly complete programmatic control of PowerShot cameras, enabling users to add features, up to and including BASIC & Lua scripting.

Some models of PowerShot cameras were affected by third-party CCD sensors with a design flaw, which caused them to fail and display severely distorted images. Canon offered to repair affected cameras free of charge.
