Yep!

see: https://bridges.torproject.org/?ipv6=True
or email bridges at torproject.org with the keyword "ipv6" in the subject or body.

But...

Right now there aren't a lot of IPv6 bridges -- some were assigned to
the email distributor, and some were assigned to the https
distributor. The latter splits bridges into 5 groups, and depending on
your source IP address you may be lucky enough to get an IPv6 bridge
[1].

Meanwhile, we hand out a few IPv6 bridges to everyone who visits
https://bridges.torproject.org, and the link to query specifically for
IPv6 addresses isn't yet publicly displayed on bridges.torproject.org
to avoid confusion/support emails.

Once there are enough [2] IPv6 bridges, the above link will be on the
front page of https://bridges.torproject.org. See:
https://tor.extc.org for an example.

p.s. It's a similar situation with obfsproxy bridges; you can request
bridges with a specified transport via
https://bridges.torproject.org/?transport=TRANSPORT_NAME, e.g.
https://bridges.torproject.org/?transport=obfs2 or adding the keywords
"transport TRANSPORT_NAME" to the body or subject of an email to
bridges at torproject.org

[1] Try requesting bridges with TorBrowser -- the set of IP addresses
corresponding to Tor exits get IPv6 (and obfs2) bridges.

[2] Every IP group has at least one IPv6 bridge
