Jo-anne Edna Mary Wilkinson, Lady Dingle CNZM (born 1957 or 1958), is a New Zealand youth worker.

[1] Once Wilkinson and Dingle returned to New Zealand, they noticed that the country had high rates of youth suicide and incarceration and decided that they wanted to do something about it.

[1] In 1995, they established the Graeme Dingle Foundation, "to give young people purpose, a positive outlook and tools to self-determine".

She has also led the foundation's research programme to confirm that their activities met objectives and positively impacted the lives of the youth undertaking them.

[5] In the 2011 Queen's Birthday Honours, Wilkinson was appointed a Member of the New Zealand Order of Merit, for services to youth.
