Djokovic has confirmed he will lead his country in their first round tie with neighbours Croatia on home soil from March 6-8.
The countries have only met once since the division of Yugoslavia in the early 1990s, with Serbia coming out on top 4-1 in a quarter-final tie – Djokovic won his singles matches against Ivan Ljubicic and Marin Cilic.
Serbia went on to win the title that season but Djokovic skipped the tournament in 2014 after they were beaten by the Czech Republic in the quarter-finals of the 2013 competition.
The 27-year-old confirmed his Davis Cup return via his official website as he set out his plans for the early part of the 2015 season.
Djokovic will open his season in the Mubadala World Tennis Championships in Abu Dhabi – the exhibition tournament he won last year as well as in 2011 and 2012.
He will then move on to Doha for the Qatar Open before heading to Australia for the first Grand Slam of the season, where he made it only as far as the quarter-finals last year.
Djokovic??finished top of the 2014 world rankings after winning the season-ending ATP World Tour Final in London, which Switzerland’s world No 2 Roger Federer forfeited on Sunday due to a back injury.
