Dmitrijs Miļkevičs (born 6 December 1981 in Riga) is a former Latvian track athlete who competed in 400 metres and 800 metres.
Miļkevičs ran a career-best 46.44 in the 400 metres at the 2003 European Athletics U23 Championships in Bydgoszcz, Poland. He has won an NCAA championship while competing for the University of Nebraska. In the 2004 Summer Olympics, he was 14th in the 800 metres. In 2006, he set the Latvian record in the 800 metres with a time of 1:43.67, a record which still stands.
After Miļkevičs found out that, due to lack of funds, the Latvian Athletics Union wouldn't able to pay for Latvian delegation's start at the 2010 European Athletics Championships, he decided not to compete.
