Potter lasted just six months in charge having replaced Champions League winner Thomas Tuchel last September.
But after a dismal runs of performances, Blues owner Todd Boehly has axed the ex-Brighton manager with the side sitting in 11th.
Potter departs having won just SEVEN of his 22 league games in charge, drawing the same amount of times while losing eight.
His last came on Saturday at home to Aston Villa, with the 2-0 defeat enough to seal his fait.
With a 1.27 points per game rate, only Glenn Hoddle faired as badly as Potter, leaving with the same PPG.
Hoddle won just 38 of his 122 games in charge, losing 43 and drawing 41.
Tuchel, who was fired four months after Boehly took over the club from Roman Abramovich, left with a 1.94 PPG rate.
In that period, he managed 63 league matches, winning 35, drawing 17 and losing 11.
But after replacing Frank Lampard in January 2021, just five months later Tuchel lifted the Champions League.

Lampard faired slightly worse off than the German in his 57 Premier League matches.
The Chelsea legend won just 28, drawing 11 and losing 18, which saw him sacked after 18 months.
Surprisingly, Avram Grant has the best PPG ratio at Chelsea when he replaced Jose Mourinho in 2007.
He managed 32 games, winning 22, drawing eight and only losing twice, reaching the Champions League final that season too.
Mourinho is behind Grant, taking charge of 212 league matches during his two stints, winning 140, drawing 44 and losing 28.
Chelsea now look to hire their 19th manager during the Prem era, with Julian Nagelsmann among the favourites to take over.
But ex-Tottenham boss Mauricio Pochettino is also in the mix with the club set to take their time, with Bruno Saltor taking up an interim role.
