Murray-Boyles also had seven rebounds and seven assists for Toronto (22-15) playing centre in place of injured starter Jakob Poeltl.
Scottie Barnes had a double-double with 18 points, 10 assists and eight rebounds as the Raptors beat the Hawks for the second game in a row.
Brandon Ingram had 19 points and nine rebounds as seven Toronto players reached double digits in scoring.
Poeltl (lower back) remained out, although Raptors head coach Darko Rajakovic confirmed pre-game that the starting centre had been cleared for contact.
Jalen Johnson and Onyeka Okongwu both had double-doubles for Atlanta (17-21). Johnson had 13 points and 14 rebounds, while Okongwu scored 17 and pulled down 12 boards.
Kristaps Porzingis returned to the Hawks’ lineup, after missing the second game of a back-to-back, scoring nine in 20 minutes off the bench.
Star guard Trae Young missed another Atlanta game as he recovers from a right quadriceps contusion.
Hawks: Although both teams struggled with their three-point shooting, Atlanta had a poor shooting night in general. The Hawks went 35-for-89 (39.3 per cent) on field-goal attempts, including 12-for-34 from beyond the arc.
Raptors: What could have been a blowout for Toronto — which led by as many as 16 points — wound up being closer with 15 Raptors turnovers leading to 23 points. Murray-Boyles was a bright spot, however, playing strong defence and showing a deft scoring touch.
Barnes’s floater with 1:48 left in the first quarter opened up a 15-point lead for Toronto, but the Hawks went on a 10-0 run to reel the hosts back in by the end of the period. That was as close as Atlanta would get in the game.
The Raptors outscored the Hawks 64-44 in the paint as Toronto went 47-for-90 (52.2 per cent) on field-goal attempts.
Hawks: Host the New Orleans Pelicans on Wednesday.
Raptors: Visit the Charlotte Hornets on Wednesday.
