The 2017 JLT One-Day Cup was the 48th season of the official List A domestic cricket competition in Australia. It was played over a four-week period at the start of the domestic season to separate its schedule from the Sheffield Shield season. The tournament was held in Sydney, Brisbane, Perth and Hobart, with all 23 matches to be broadcast live on the Cricket Australia website and app. It was the first time in more than a decade that neither the Nine Network nor Fox Sports (Australia) have hosted a television broadcast of the tournament. The tournament was sponsored by Jardine Lloyd Thompson.
