"Everything in My Heart" is a song by Canadian singer Corey Hart. It was released in November 1985 as the third single from Hart's sophomore album, Boy in the Box. The second chart-topper from the album (after "Never Surrender"), "Everything In My Heart" hit CAN #1 on January 18, 1986 (RPM) and was CRIA-certified Gold on January 29, 1986 (Music Canada).
On February 1, 1986, the same day that its parent album, 'Boy In The Box', was CRIA-certified Diamond for domestic shipments of one million units, "Everything In My Heart" peaked at US #30 (Billboard Hot 100).
The single was originally pressed in translucent red vinyl and its b-side featured a live recording of the seasonal Gene Autry Christmas classic, "Rudolph the Red Nosed Reindeer".
The music video was directed by Rob Quartly and was filmed in Boston.
