Anthony Dale Modra (born 1 March 1969) is a former Australian rules footballer who represented Adelaide and Fremantle in the Australian Football League (AFL) and West Adelaide in the South Australian National Football League (SANFL). Known for his spectacular marking ability in the full-forward position, Modra had the physical strength and size to match the best opposition full-backs in the competition. As of 2023, he is the only Adelaide player to kick more than 100 goals in a season, achieving the feat in 1993 by registering 129 goals for the year.

Modra was born in McLaren Vale, South Australia, but grew up nearby in Christies Beach, South Australia, and attended Christies Beach Primary School along with future Adelaide teammate Nigel Smart. He moved to Loxton, South Australia, at age 11 with his parents (Douglas and Valerie) and four older siblings (Kerry, Kym, Rick and Joanne). Modra grew up playing multiple sports—notably Australian rules football and soccer for Loxton, both of which he loved equally—but solely played Australian rules football from age 14, which most of his friends played. Growing up, Modra supported Glenelg in the SANFL, plus St Kilda and Richmond in the VFL (prior to it merging into the AFL).

Modra first played Under-19s game for West Adelaide in 1988 but could not adjust to working and playing football in Adelaide. Modra returned home, and in 1989, as a 20-year-old, Tony kicked 76 goals for the Loxton Football Club; Loxton would end up losing the Grand Final to Barmera-Monash.

In 1990, Tony joined his brothers Rick and Kym at the Renmark Rovers Football Club in pursuit of a premiership. Modra led the team to win the 1990 Riverland Football League in a grand final replay after drawing with Waikerie the previous week. Modra kicked a remarkable 118 goals for the season.

In 1991, Modra attempted to move to Red Cliffs in the Sunraysia Football League and played one pre-season game for the club, kicking 13 goals on newly Sydney-drafted Darren Holmes. However, Modra was still contracted to West Adelaide, and they would not be awarded a fee if Modra was to play in the AFL one day. Due to Red Cliffs being based interstate, this fee would not be received if Modra played there. Lawyers from Red Cliffs faced a tribunal in Adelaide, but the tribunal ruled that Modra was a contracted West Adelaide player. Reluctantly, he returned to West Adelaide for the 1991 season, playing in the losing 1991 SANFL Grand Final. He did enough to earn an invite to an Adelaide Crows training session, and he managed to win selection in the squad. Modra was selected in the 1991 AFL draft as a Zone Selection for the Adelaide Football Club. Modra played 15 SANFL games for West Adelaide and kicked 46 goals between 1988 and 1991.

Modra began his AFL career at 23 years of age. At first, his potential at full-forward was overshadowed by senior player Scott Hodges, who had a reputation as a prolific goalkicker in the SANFL with Port Adelaide Football Club, having broken the record for most goals in a season in 1990 when he kicked 153. Modra played 8 games in his debut season of 1992, kicking 21 goals.

At the start of 1993, an injury to Hodges led to Modra's inclusion at full-forward with Adelaide. Modra was an instant success, kicking 10 goals in the opening round against Richmond at Melbourne Cricket Ground and finishing the year as runner-up to Geelong's Gary Ablett Sr. in the Coleman Medal with 119 goals in the home-and-away season, kicking an additional 10 in 3 finals.

Both the Crows and Modra had less successful seasons in 1994 through to 1996, although Modra topped the club goalkicking each year. Also in 1994, Modra garnered controversy when he insulted a female flight attendant while on a flight from Hong Kong. Modra apologised for the incident, citing his 'nightlife' as the cause, and was given fines by both the Adelaide Crows and the AFL.
