2016–17 Southern Combination Football League

The 2016–17 Southern Combination Football League season was the 92nd in the history of the competition, which lies at levels 9 and 10 of the English football league system.

Premier Division featured 17 clubs which competed in the division last season, along with three new clubs:

• Crawley Down Gatwick, promoted from Division One
• Haywards Heath Town, promoted from Division One
• Peacehaven & Telscombe, relegated from the Isthmian League

Also, Wick & Barnham reverted to their original name of Wick.

Haywards Heath Town, Horsham YMCA, Pagham and Shoreham applied for promotion to Step 4 for 2017–18. While Haywards Heath Town won the league, they were subsequently charged by the FA for playing a suspended player. On 22 May, it was announced that Haywards Heath had 9 points deducted, which would hand the title and promotion to Shoreham. Haywards Heath's appeal was ultimately dismissed on 15 June, therefore Shoreham's championship and promotion were confirmed.

Division One featured 14 clubs which competed in the division last season, along with four new clubs:

• AFC Varndeanians, promoted from Division Two

• Billingshurst, promoted from Division Two

• East Preston, relegated from the Premier Division

• St Francis Rangers, relegated from the Premier Division

• Little Common could not be promoted as arranging a groundshare with another club in order to secure promotion was not allowed. This resulted in a reprieve for AFC Uckfield Town.

Division Two featured twelve clubs which competed in the division last season, along with four new clubs:

• Jarvis Brook, promoted from the Mid-Sussex League
• Lancing United, promoted from the West Sussex League
• Sidlesham, demoted from Division One
• Worthing Town Leisure, promoted from the Brighton, Worthing & District League, and a merger between Worthing Town F.C. and Worthing Leisure F.C.

A.F.C. Roffey Club withdrew from the league in August 2016 without playing a match.

Promotion from this division depends on ground grading, and neither Bosham nor Jarvis Brook had the required grading. This resulted in reprieves for AFC Varndeanians and St Francis Rangers from Division One.
