Chisnall lost in the last 16 of the World Championship for the second successive year in 2013. He came from a set down three times against Simon Whitlock to force a deciding set which he led 3–2, before Whitlock took out a crucial 152 finish and then won two successive legs to knock Chisnall out. He reached the final of the first UK Open Qualifier of the year, but lost 6–2 to Michael van Gerwen. At the UK Open itself he lost 9–2 to James Wade in the fourth round, and at the European Championship he was whitewashed 6–0 by Jamie Caven in the first round who averaged 106. At the World Matchplay he saw off Paul Nicholson 10–8 and gained revenge over Caven by defeating him 13–10 to reach the quarter-finals of the event for the first time. He played Michael van Gerwen and had chances to move 7–3 ahead but missed and even though he took out a finish of 144 and had an 11 dart leg he was beaten 16–11. In September, Chisnall won his first title since November last year at the German Darts Championship. He required deciding legs to advance through each of his first four matches, before beating Steve Beaton 6–4 in the semi-finals with an average of 106.30 and Peter Wright 6–2 in the final. He called the title the highlight of his career to date and moved up to a career high seventh on the Order of Merit. Chisnall faced Wright in a final for the second consecutive tournament at the seventh Players Championship of the season in Barnsley and won again, this time by a 6–5 scoreline.
