Adi bin Said (born 15 October 1990) is a Bruneian professional footballer who plays as a striker for Brunei Super League club Kasuka. He has played in Malaysia.

Adi began his footballing career with Manggis United, coached by former Brunei forward Majidi Ghani. He joined newly promoted Majra FC in 2007 and played for them in the Brunei Premier League until 2012, when his exploits on the international scene attracted Brunei's sole professional club DPMM FC to sign him for the 2012 S.League season. He scored his first goal for DPMM against Warriors FC on 23 June that year.

Adi saw much playing time as a substitute in the following season, but the squad played underwhelmingly and finished in eighth place, costing Vjeran Simunic his job. Adi's new coach Steve Kean in contrast was more reluctant to utilise him, restricting Adi to only 10 appearances in the 2014 S.League. However, he made most of his chances count, scoring in the final of the League Cup, and netting two braces against Hougang United and Woodlands Wellington in an August purple patch.

After a quiet 2015, Adi was given starts in all of DPMM's domestic cup matches for the 2016 campaign. He scored with a direct free kick in a 2–1 win over Tampines Rovers in the 2016 Singapore League Cup on 21 July.

Adi scored 8 goals in all competitions in a largely disappointing 2017, to finish behind Rafael Ramazotti in the club's goalscoring tally for the year. The following season, Adi started ahead of elder brother and new captain Shahrazen in a new 4-3-3 formation deployed by Brazilian coach Renê Weber. Adi finished the season with 11 goals and 10 assists, making him joint-top assist-maker of the league, the other being Riku Moriyasu of Albirex Niigata (S).

After a successful trial in December 2018 (including scoring a hat-trick in a friendly), Adi signed a one-year contract with Malaysia Premier League side UiTM FC, becoming the first Bruneian local-born expatriate footballer ever. He scored within twenty seconds of his debut in a 1–3 victory against PDRM FA on 1 February, managing to get into the scoresheet twice. After two goals and six assists, he was released by UiTM FC in late May.

Two months later, Adi returned to DPMM FC and made his first appearance since coming back in the 3–3 draw against Warriors FC on 6 July. He scored his first goal since his return in the 3–0 victory over Geylang International on 2 August, in a game where his younger brother Hakeme debuted for the first team and shared a scoresheet with. He netted a brace in the penultimate league fixture which was a 5–4 home win against Hougang United on 29 September.

At the start of the 2020 Brunei Super League, Adi left DPMM to join Kota Ranger FC, reuniting him with his brother Amalul Said. He also became the team captain, taking over from Afi Aminuddin. He made his debut at the 2020 Piala Sumbangsih on 8 February, scoring a hat-trick against MS ABDB. A month later, he scored a brace in Kota Ranger's first fixture of the 2020 Brunei Super League, a 7–0 win over Setia Perdana on 2 March. However after scoring yet another goal against IKLS-MB5 the following week, the league was stopped and discontinued due to the COVID-19 pandemic.
