Dolphin Coloring Pages
Make free printable dolphin coloring pages from 12 dolphin pictures we drew ourselves: a jumping dolphin, a pod of three, a mother and calf, a big dolphin face, a dolphin in the waves, a dolphin under the sea with fish and seaweed, a cute round dolphin, a dolphin at sunset, two dolphins leaping round a heart, a swimming dolphin, a dolphin over a coral reef and an easy dolphin for little ones. Every dolphin is our own simple drawing, with no film or cartoon dolphins, no named animals, parks or teams and no brands, so the pages suit homes, classrooms and libraries. Print one big dolphin on a page, a grid of four or six small ones, a sea scene with three leaping dolphins, a fold-in-half card, or a dolphin mandala with small dolphins round the edge and a new pattern at the press of a button. Blank dolphins to design prints 1, 2, 4 or 6 plain dolphin outlines with no eye or markings, so children can draw their own; one fills a 186 mm square on US Letter. Type a child’s name for a name page, or paste a class list to get the same dolphin for everyone with each name at the top. Choose simple, medium or detailed lines, never thinner than 0.5 mm. Download one multi-page PDF for US Letter or A4, a 300 DPI PNG of every page, or an SVG. No sign-up, no watermark.

Dolphin facts to read while you color
- Dolphin calves stay close to their mothers. NOAA Fisheries says common bottlenose dolphin calves nurse for about 20 months and generally stay with their mothers for 3 to 6 years.
- Bottlenose dolphins may travel alone or in groups, and the groups often break apart and reform. They find prey by listening and by echolocation.
Source: NOAA Fisheries, common bottlenose dolphin species page, read 9 November 2026.
Coloring ideas
- Bottlenose grey: a darker grey back and a pale grey or white belly below the belly line.
- Sunset sea: orange and pink sky, a yellow sun and deep blue water.
- Coral reef: bright corals, a sandy seabed and blue-green water.
Printing tips
- Every page keeps a 12.7 mm (half inch) margin from the paper edge, on US Letter and A4.
- Plain paper is fine for crayons and pencils; use thicker paper or card for markers or paint.
- Print one page first and check it before printing a whole pack or class set.
- Choose Detailed lines only with fine pens or sharp pencils, and Simple lines with chunky crayons.
