Outcast is a 2007 children's fantasy adventure novel written by Michelle Paver and illustrated by Geoff Taylor.

It is preceded by Wolf Brother (2004), Spirit Walker (2005), and Soul Eater (2006), and followed by Oath Breaker (2008), Ghost Hunter (2009), Viper's Daughter (2020), Skin Taker (2021), and Wolfbane (2022).

Later, Torak, Renn, Bale and Fin-Kedinn deduce that there is only one fragment of the fire opal left somewhere in the forest, which Thiazzi and Eostra, the remaining Soul Eaters, are both looking for.

Kirkus Reviews provided less praise for Outcast than for previous novels in the series, noting that "the plot’s most dramatic elements [...] take a back seat to character development".

They further discussed how "the vividly interwoven natural and spiritual settings that have distinguished this series emerge in long stretches seen from the point-of-view of Wolf".
