DELTARUNE Chapter 5 OST
DELTARUNE Chapter 5 OST is the upcoming official soundtrack for Chapter 5 of Deltarune. It will be released alongside Chapter 5 on June 24, 2026. On Steam, the DELTARUNE Soundtrack is planned to be combined with the prior Chapter albums, being a free update to the current soundtrack.[1]
In the Chapter 5 release newsletter, Toby Fox revealed that significantly more guest musicians contributed to this Chapter.[2] He had also stated that the track names are also spoilers.
Two tracks from Chapter 5 have been released. Stealth,[note 1] a formerly cut track originally planned for sneaking scenes in Chapter 3,[3] will play during the optional scenes with the Mikes in Chapter 5.[4][5] Shop 3,[note 1] a variant of kris_piano_shop, will play for most of the remaining shopkeepers, and is the only other song that "doesn't spoil something", according to Toby Fox.[6]

Even if you use other platforms, I recommend buying the soundtrack on Steam. I'll be updating the soundtrack every time a new Chapter comes out, so it'll be a really good deal.

That being said, as an act of goodwill, I would like to spoil one optional Castle Town scene. This scene assumes you have seen the Special Room in Chapter 4...
