In the Juncker Commission, Hahn was nominated to oversee the Union's enlargement and neighbourhood policies, now managed by a single Directorate-General of the European Commission, DG NEAR.

In his new portfolio, Commissioner Hahn launched, together with High Representative Federica Mogherini, a comprehensive reform of the European Neighbourhood Policy (ENP), as mandated by Commission President Jean-Claude Juncker.

As Commissioner for Enlargement and Neighbourhood, Hahn oversaw the Union's response to the Syrian and Libyan civil wars and the war in Ukraine.
He also oversaw, together with his colleagues, the EU's emergency response to the refugee crisis along the Balkan route, and managed the relations with Turkey before and after the failed 2016 coup, including in terms of assistance to the Syrian refugees based on the EU-Turkey deal.

On 24 November 2016 Johannes Hahn signed the agreement on financing the European Union Anti-Corruption Initiative in Ukraine.

When European Commissioner for Regional Policy Corina Creţu stepped down from the European Commission to take up her seat in the European Parliament following the 2019 elections, the Commission's President of the European Commission Jean-Claude Juncker announced that her portfolio would be transferred to Hahn.
Shortly after, Austria's interim Chancellor Brigitte Bierlein announced her government's intention to put forward Hahn for a third term as the country's representative in the European Commission.
