Pialligo (postcode: 2609) (/pɪæləɡoʊ/) is a rural suburb of Canberra, Australian Capital Territory, Australia.

[2] Beltana Road in Pialligo is home to many of Canberra's nurseries.

Quaternary alluvium covers the main western part of Pialligo.

This is a significant place, because in the bed of the creek the Rev W B Clarke first recognised Silurian fossils.

[3] Aside from the city's design, arguably Walter Burley Griffin's longest-living legacy in Canberra is the forest of Redwood trees (both Sequoia sempervirens and Sequoiadendron giganteum) that was planted in 1918 by Walter Burley Griffin and arborist Thomas Charles Weston on Pialligo Avenue.
