0 Avenue (Zero Avenue) is a road in the Lower Mainland, British Columbia, running beside the Canada–United States border from Surrey to Abbotsford. The road runs parallel to the border between the two countries.

The road begins near the Peace Arch Border Crossing, and continues eastward for 28.9 kilometres (18.0 mi), with gaps around the Pacific Highway and Lynden–Aldergrove Border Crossings. Boundary Road on the US side runs for 1.5 miles (2.4 km) along 0 Avenue and again one mile (1.6 km) to the west, with many cameras watching the border, before the U.S. road ends at the Lynden–Aldergrove Border Crossing. 0 Avenue continues west along the northern border of Peace Arch Historical State Park to Peace Arch Crossing. Small pedestrian bridges cross a trench on the border. At the eastern end of 0 Avenue, the road turns north.

In 1858, after creating a 1.5-mile (2.4 km) road from White Rock, along the beach through the Semiahmoo Indian Reserve, a border trail was created by Royal Engineers and American surveyors. The trail ran east and is the precursor to the modern 0 Avenue.

The road is used by smugglers, even though the border controls have tightened up since the September 11 attacks. The first known drug tunnel along the Canada–United States border was found east of the Lynden–Aldergrove crossing in 2005. Some asylum seekers have also tried to move to Canada from the U.S. via 0 Avenue.

During the COVID-19 pandemic, restrictions on cross-border travel made 0 Avenue a meeting place for several cross-border couples. Once restrictions were lifted, some of these couples married at Peace Arch Park, a transnational park between Blaine and Surrey.
