The Canadian province of Alberta has a provincial highway network consisting of over of roads as of 2021-2022, of which have been paved.

All of Alberta's provincial highways are maintained by the Ministry of Transportation and Economic Corridors, a department of the Government of Alberta. The network includes two distinct series of numbered highways:

The 1–216 series (formerly known as primary highways), making up Alberta's core highway network—typically paved and with the highest traffic volume The 500–986 series, providing more local and rural access, with a higher proportion of gravel surfaces

1–216 series

Alberta's 1 to 216 series of provincial highways are Alberta's main highways. They are numbered from 1 to 100, with the exception of the ring roads around Calgary and Edmonton, which are numbered 201 and 216 respectively. The numbers applied to these highways are derived from compounding the assigned numbers of the core north–south and east–west highways that intersect with the rings roads. In Calgary, Highway 201 is derived from the north-south Highway 2 and the east-west Highway 1. In Edmonton, Highway 216 is derived from the same north-south Highway 2 and the east-west Highway 16.

Within this series, all or portions of Highways 1, 2, 3, 4, 9, 15, 16, 28, 28A, 35, 43, 49, 63, 201 and 216 are designated core routes of Canada's National Highway System (NHS). Highway 28 from Highway 63 to Cold Lake is designated a NHS feeder route and Highway 58 between Rainbow Lake and Highway 88 is designated a NHS northern/remote route.

Highways 1, 2, 3, 4, 16, and 43 are considered Alberta's most important interprovincial and international highways and are divided highways for much or all of their length. Speed limits are generally divided highways/freeways and on others, while segments of Highway 1 and Highway 16 through the national parks within Alberta's Rockies have speed limits varying between .

The Highway 15/28A/28/63 corridor between Edmonton and Fort McMurray is considered one of Alberta's most important intraprovincial highways. It is vital to the oilsands operation.

The vast majority of the highways within the 1 to 216 series of highways are two-laned and paved, while Highways 1, 2, 3, 4, 11, 15, 16, 43, 60, 63, 100, 201, and 216 are twinned (expressways) for most of their length. Only four highways within the series have segments that remained gravelled. These include segments of Highways 40, 58, and 68 and a short segment near the northern terminus of Highway 63.

Highways 1 and 16 are Trans-Canada Highway routes and are signed with TCH shields, not standard provincial shields.

X series The roads in the X series are typically highways that are planned realignments or spurs of existing highways. The numbers applied to each highway in the X series are derived from the highway that is planned for realignment or spurred from (e.g. Highway 16X will be a realignment of Highway 16, and Highway 10X is spur from Highway 10).

500–986 series

The 500/600 highways are east–west roads where the numbering increases northward from the Montana border to the Northwest Territories border. The 700/800 highways are north–south roads where numbering increases eastward from the British Columbia border to the Saskatchewan border. The 900 highways are newer or planned roads that have been established for future consideration as or as potential extensions or realignments of highways within the 1–216 series.

Some of these highways are paved, while others are entirely or partially gravel. Rural speed limits range from .
