NBA Longest Losing Streaks - Regular Season

This is the list with the all-time worst losing streaks in NBA history in the regular season.

The 2010-11 Cleveland Cavaliers could not survive the departure of LeBron James and had the worst losing streak ever in the NBA with 26 consecutive losses. They were alone at the top for a couple of years until the Philadelphia 76ers tied them in 2013-14, also losing 26 in a row.

The Bobcats didn't make his owner Michael Jordan very proud in 2012-13, losing 18 straight games.

The 2015-16 76ers have the longest losing streak ever if you take into account streaks that spanned over 2 seasons and count the 10 losses that closed their 2014-15 season.
