ARCA races at Iowa

Stock car racing events in the ARCA Menards Series have been held at Iowa Speedway, in Newton, Iowa during numerous seasons and times of year since 2006.

The Shore Lunch 150 was an ARCA Menards Series race held at Iowa Speedway in Newton, Iowa. The inaugural race was held on October 15, 2006 and was 250 laps in length. The race was shortened to 200 laps in 2009 and 150 laps in 2013. From 2015 to 2020, the race was held on the same weekend as the IndyCar Series race at Iowa.

The Atlas 150 is an ARCA Menards Series/ARCA Menards Series East combination race held at Iowa Speedway in Newton, Iowa.

The ARCA Menards Series East, formerly the NASCAR K&N Pro Series East, joined the ARCA Menards Series in this race starting in 2021 and it became one of three combination races for the two series, the others being Milwaukee and Bristol.

The Casey's General Store 150 was a NASCAR K&N Pro Series East and NASCAR K&N Pro Series West combined race held annually at Iowa Speedway. From 2007 to 2010, it was a 175-mile (282 km) race. In 2010, it was a 153.1-mile (246.4 km) race. From 2012, it was reduced to 131.2 miles (211.1 km).

From 2007 through 2016 there were two different winners in the race (one in the East and the other in the West). The overall winner received the win in the series that the driver was eligible for points while the best placed driver from the other series also received the win (in the other series). Starting at 2017, the overall winner receives two separate wins (one in the East and the other in the West).

Starting in 2011 the race became a support race for the NASCAR Xfinity Series weekend.
