The 1983-84 UEFA European Cup Semi-Final between Liverpool of England and Dinamo Bucharest of Romania was one of two association football ties that made up the penultimate round of the 1983–84 European Cup, Europe's primary club football competition. Liverpool, who had won the competition three times, were appearing in their fifth semi-final, while it was Dinamo Bucharest's first and only appearance at this stage of the competition. The other semi-final in the competition that year was contested between Dundee United and Roma. Liverpool won the tie 3–1 on aggregate, and went on to be crowned European champions after beating Roma in the final. The tie has been described as one of Liverpool's "finest hours", in the face of "bitterly effective opposition" from Dinamo.
