In the UK there are two explicitly nationalist political parties, Plaid Cymru and the SNP, that curiously advocate handing sovereignty to the EU.
Are there nationalist parties anywhere else in the world that advocate for something similar?

The premise of this question is flawed as one user put it;
Plaid and the SNP do not consider joining the EU to be ceding sovereignty, they believe that it enhances it. As part of a larger group, with power such a veto, they have more control over their own destiny than they do alone.
Even accepting the broad sweep of the Questioners' position then yes, there are a number of similar examples available.
The most obvious direct comparison is Catalonia, the El Periodico poll table includes one poll that specifically asked for support for independence if it meant exclusion from the EU, it showed support dropping by 10%.
Other similar groups exist in Kosovo, a number of the sub-parties within the ruling Alliance for the Future party are described as nationalist, and Kosovo wants to be an EU member.
Looking further afield, the logic in the question would apply to the Six Californias proposal in the US. In this case the "nationalist" groups no longer want to be controlled by the state of California, but would be handing sovereignty to the US.
