The record for the longest unbeaten streak in Test cricket is held by the West Indies, who remained undefeated for 27 consecutive Test matches from January 1982 to December 1984.
During this period, the West Indies team, under the captaincy of Clive Lloyd and later Vivian Richards, dominated international cricket with a formidable lineup, particularly renowned for their fast-bowling attack and strong batting order.
This remarkable achievement underscores the West Indies' dominance in Test cricket during the early 1980s, a period often regarded as one of the golden eras in cricket history.
