Abaton is a double album by Swiss pianist and composer Sylvie Courvoisier, recorded in September 2002 and released on ECM the following year, featuring one disc of compositions and one of improvisations.

Thom Jurek of AllMusic writes the two discs are "very different" but "nonetheless dovetail to offer a solid portrait of a composer-led group that views stasis and movement with equanimity.

"[1] "Ianicum" opens with Courvoisier playing a single lower-register pitch on her piano which is repeated and answered by the other members of the trio in brief phrases before turning into a twinned line "where left and right hands move seemingly in opposition yet with such restraint that the music is seamless.

"[1] AllMusic awarded the album 4½ stars and in its review by Thom Jurek, he states "Abaton is Courvoisier's crowning achievement thus far, and this group points her firmly forward in a direction where everything is still possible, demonstrating that there is something new under the sun in classical music and improvisation.

"[1] In JazzTimes, Andrew Lindemann Malone wrote "It's rare to hear modern classical music forged anew in the heat of improvisation, but that's exactly what Abaton does.
