"Matemateāone" (English: "Deep Affection") is a song by New Zealand musician Stan Walker.

A love ballad, the song's music video celebrates his marriage to his partner Lou Tyson.

In 2014, Walker collaborated with the musicians Ria Hall, Troy Kingi and Maisey Rika on the single "Aotearoa", a Māori language song released to mark te Wiki o te Reo Māori, as a challenge to release the second song in history (after "Poi E" (1984) by the Pātea Māori Club) to top the New Zealand charts.
