The 2009–10 season was Tottenham Hotspur's 18th season in the Premier League. It was their 32nd successive season in the top division of the English football league system.

Tottenham began the season under the stewardship of veteran manager Harry Redknapp in his first full season at the club. Relative to previous seasons, Tottenham's transfer dealings were limited, with only seven players brought in during the two transfer windows; 16 players left White Hart Lane over the course of the season.

They accumulated 70 points and finished the season with an average attendance of 35,794 for the second season running, the ninth-highest in the Premier League.
