The Wide Bay Pipeline is a transmission pipeline located in central Queensland. The pipeline is owned by Australian Gas Networks (AGN) and is operated by the AGI O&M Services Pty Ltd.

The Wide Bay Pipeline is 275 km in length, nominal diameter of 114 mm, and has a capacity of 6.1 TJ/day. The pipeline transports gas from Maryborough to Rockhampton via Bundaberg and Gladstone in Queensland.

The Wide Bay Pipeline is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Part 10 of the National Gas Rules (NGR). It was previously subject to the access regime for non-scheme pipelines under the former Part 23 of the NGR, which was replaced by Part 10.

The AER has granted the following exemptions for the Wide Bay Pipeline:

• On 13 December 2017, a five year Category 2 and Category 3 exemption under Part 23 of the NGR.
• On 30 November 2022, a five year Category 3 exemption under Part 23 of the NGR. Due to reforms to the NGR, the exemption transitioned to a Category 2 exemption under Part 10 of the NGR.
• On 30 November 2022, a Part 24 Category 2 Exemption of the NGR until 12 December 2027.
