The oldest record which names the village is dated 963 AD. It records a grant of land in Sherburn-in-Elmet and nearby settlements by King Eadgar to Aelsac as a reward for goods and services. The land granted in Hillam is described as, "on Hillum tyesra oxena gang" meaning "in Hillam two oxgangs". An oxgang was the related to the amount of land an ox could plough in a year and is roughly equated to 15 acres.
The village is served by a public house, The Cross Keys, winner of Leeds City Council Business in Bloom Gold award in 2007 and Yorkshire in Bloom Gold Award in 2007. The Ring Tree is lit at Christmas and local children gather to enjoy a Christmas celebration each year. Due to disease the flowering horse-chestnut tree was felled in May 2016 and replaced with a Whitebeam tree in November 2016. Hillam Historians restored the village pump in Hillam Square during 2006. Hillam Square retains its red telephone box. In spring 2017 a defibrillator was installed.
