Adopted 19 September 1983, the flag shows green and red triangles divided by a black diagonal band edged in yellow with two white stars. Green symbolises fertility; red struggle and heritage; black the people; yellow sunshine; the stars hope, liberty, and the twin‑island federation. Protocol governs use and half‑masting.
Saint Kitts and Nevis adopted its flag at independence on 19 September 1983 following a national design competition, with Edrice Lewis’s entry selected. The banner conveys both unity and duality across the federation’s two islands.
Two triangles—green above for the islands’ fertility and landscape, red below for the struggle against slavery and colonialism—are divided by a black diagonal band edged in yellow. On the band sit two white five‑pointed stars. The black stands for the people and their strength; the yellow for year‑round sunshine; the stars for hope and liberty and for Saint Kitts and Nevis as coequal parts of a single state.
Government guidance fixes proportions, construction, and colour references; protocol requires respectful handling, correct precedence with foreign flags, and dignified retirement. The flag is central to Independence Day observances and daily display at ministries, schools, and missions abroad; half‑masting follows executive order.
