Taking place in Monaco, the draw followed its usual format. The 32 competing teams were split into pots (1-4), with one side from each pot assigned to each of the eight groups (A-H).
Liverpool are to meet Napoli in the group for the second year in a row, but will consider their path to the knockout stages a favourable one, with Red Bull Salzburg and Genk.
English champions Manchester City have been paired with Shakhtar Donetsk again, as well as Croatia's Dinamo Zagreb and Champions League debutants Atalanta.
Elsewhere, Real Madrid and Paris Saint-Germain will meet in two heavyweight clashes in Group A, but Galatasaray could threaten to make it tricky for either of them.
Group H promises to be a very competitive one, with Chelsea, Ajax, Valencia and Lille, with any in with a chance of qualifying. But this year's 'Group of Death' is arguably F after Barcelona, Borussia Dortmund and Inter were drawn with Czech minnows Slavia Prague.
