Gustavus Hamilton (1739 – 1775) was an Irish miniature painter. He was the son of Rev. Gustavus Hamilton, vicar of Errigal and rector of Gallon, County Meath.

One of his teachers was Irish painter Robert West. He was also an apprentice or pupil of Samuel Dixon of Capel Street, Dublin, where he was employed in colouring the basso-relievo prints of birds and flowers produced by Dixon.

His paintings are typically signed with his initials, with "ham." coupled with date, or as "Gus. Hamilton, sometimes with and sometimes without a date. His draftsmanship has been criticized as sometimes poor. He is known for his portrait's faces sometimes having a bluish cast.
