The Scilly Isles Novices' Chase is a Grade 1 National Huntchase in Great Britain which is open to horses aged five years or older. It is run at Sandown Park over a distance of about 2 miles and 4½ furlongs (4,124 metres), and during its running there are seventeen fences to be jumped. The race is for novice chasers, and it is scheduled to take place each year in late January or early February. It was sponsored by The Tote in 2011 and run as the Totepool Challengers Novices' Chase, and by Betfair in 2012 and run as the Betfair Novices' Chase. The 2013 running was sponsored by Betfred and run as the Betfred Mobile Lotto Challengers' Novice Chase. The race is still sponsored by Betfred and the Scilly Isles name was restored to the race title from 2014.
The race was first run in 1964 and takes its name from the Scilly Isles, Surrey, an area near to Sandown Park racecourse.
Prior to 1988 the distance of the race was 2 miles and 18 yards (3,235 metres).
