Hannukah, being eight days long, could have Hanukkah fall on two shabbatot when Hannukah begins on Shabbat. (This happens in December 2026, December 2027 and December 2030.) When this happens, this is the Haftarah read on the first of the two Shabbatot. The Haftarah for the second Shabbat of Hannukah can be found here.
If there is only one Shabbat Hannukah we read this Haftarah.
