The 2010–11 season was Aberdeen's 98th season in the top flight of Scottish football and their 100th season overall. Aberdeen competed in the Scottish Premier League, Scottish Cup and Scottish League Cup. Aberdeen began the season with successive league wins over Hamilton Academical and St Johnstone, but suffered a poor run of form in the following months, culminating in a club record 0–9 defeat to Celtic in November 2010. The following month, Mark McGhee was sacked as manager and replaced by Motherwell manager Craig Brown.
