Ecco the Dolphin is a series of action-adventure video games developed by Appaloosa Interactive (previously known as Novotrade International) and published by Sega. They were originally developed for the Mega Drive/Genesis and Dreamcast video game consoles, and have been ported to numerous systems. The story follows the eponymous Ecco, a bottlenose dolphin, who fights extraterrestrial threats to the world. The games are known for their high difficulty.^[1][2] Ecco was created by Ed Annunziata,^[3] who also produced Chakan: The Forever Man, which was also released in December 1992.

Released in 1992, the original game followed the exploits of a young dolphin named Ecco as he searches the seas, and eventually time itself, for his missing pod.

Released in 1994, the sequel follows Ecco's exploits after the conclusion of the original game as he travels the oceans, the past, and the future in his quest to save the planet once more.

Released in 1995, this title was intended as edutainment and was less difficult than the previous two titles in series.

When Ecco and his friends find out Big Blue, a wise and famous whale, is nearby, they must do favors and break crystals in order to pass the stage and find him.

Released in 1995, an edutainment game similar to Ecco Jr. on the Sega Genesis, this title was released on the Sega Pico. In this game, Ecco and his pals explore the ocean and the ruins that lie within to find various treasures. This game distinguishes itself by utilizing stylus control for the gameplay.

Released in 2000 for the Dreamcast and later ported to PlayStation 2, this title re-envisions the Ecco mythos in a new Earth with a new premise.^[4]

A sequel to Defender of the Future was in development in 2001, but was cancelled due to the decline of the Dreamcast. A playable build of the game was leaked online in 2016.^[5][6]

Ecco the Dolphin and Ecco: The Tides of Time were both re-released for the Sega CD, Master System and Game Gear, and Defender of the Future was originally released for the Dreamcast and later re-released for the PlayStation 2. The Sega CD version of Ecco the Dolphin was ported to Microsoft Windows in 1995. Ecco the Dolphin was also re-released on the Game Boy Advance as part of the fourth Sega Smash Pack. Ecco the Dolphin, Ecco: The Tides of Time, and Ecco Jr. can be found on the PlayStation 2 and PlayStation Portable game Sega Genesis Collection. All of the Mega Drive games have been released on Valve's Steam platform,^[7][8][9] as well as being ported to Nintendo's Virtual Console^[10] and the first game was ported to Microsoft's Xbox Live Arcade.^[11]

Two six-part comic book series of Ecco the Dolphin stories based on the first game were featured in Sonic the Comic in 1993 and 1995. Series one was written by Woodrow Phoenix the first two issues were drawn by Chris Webster, Steve White provided art for the remainder of the series. Alan Mckenzie wrote series 2.

In late 2016 series creator Ed Annunziata reached a settlement with Sega regarding the legal rights to the franchise. The attempt to regain the intellectual property rights, in part, arose from Annunziata's unsuccessful attempt to make a spiritual successor called The Big Blue funded through Kickstarter which could not use the Ecco name. Although the exact details of the settlement were unclear, it was believed by media outlets including Venture Beat that it could pave the way for a new installment in the franchise by Annunziata.^[12] Soon thereafter, Annunziata himself talked about wanting to revive the series for the Nintendo Switch.^[13] In a 2019 interview he addressed the Big Blue project, commenting "I still very strongly believe in the story and the mechanics, but it really can't be a spiritual successor to Ecco, it has to be Ecco! One thing I can say is in the future, people are playing this game. I never give up!"^[14]
