Zachary Elias Auguste (Greek: Ζαχαρίας Ηλίας "Ζακ" Όγκαστ;[1] born July 8, 1993) is a Greek-American[2][3] professional basketball player for SeaHorses Mikawa of the B.League.

After graduating from New Hampton, Auguste enrolled in the University of Notre Dame, to play college basketball for the Fighting Irish.

[5] As a junior in 2009–10, Auguste averaged 22 points and received All-Star accolades from the Mid-Wachusett (Central Massachusetts) league and local newspapers the Telegram & Gazette and The MetroWest Daily News.

[5] After adapting to the higher competition level, he improved dramatically in time, putting on 28 pounds and developing his post game to transition from a perimeter player to a forward.

[12][13] Sources: Auguste made his debut for Notre Dame in a November 12, 2012 victory against Monmouth, contributing 4 points and 3 rebounds in 3 minutes.

[6][21] For the 2013–14 season, Auguste was expected to play a larger role after Cooley graduated and coach Mike Brey cited him as a major player.

A memorable December 13, 2014 game against Florida State, in which he scored a career-high 26 points, started what coach Brey described as a run of key contributions from the forward,[25][26] with Auguste quickly recouping from his bad performances.

[20][26][30] In the Round of 64 of the following 2015 NCAA tournament, Auguste scored 25 points against Northeastern, including two under-pressure free-throws in the final minute of a 69–65 close-fought win.

Butler did not score, and in overtime Auguste blocked a shot before grabbing a rebound – a team-leading 13th – as Notre Dame won to reach the Sweet 16.

[32][33] A comfortable win over Wichita State followed (15 points, 6 rebounds and 1 block for Auguste in 26 minutes) and Notre Dame qualified to the Elite Eight for the first time since 1979.

[34] Auguste, described as "Notre Dame's only true post player", was predicted to play an important role in the game against undefeated Kentucky, who – in Karl-Anthony Towns and Willie Cauley-Stein – had some of the biggest forwards of the tournament.

[47] On August 29, 2016, he signed a contract with the Lakers,[47] but he was waived on October 12, without playing in any regular season NBA games with the team.

[55] On July 20, 2020, Auguste officially returned to the Greek Basket League and Panathinaikos for a second stint with the EuroLeague club, signing a two-year (1+1) contract.

[56] He played for the Boston Celtics in the 2021 NBA summer league, scoring 2 points on 1–2 shooting and taking 5 rebounds in 16-minutes at his debut, a 85–83 win against the Atlanta Hawks.
