Given I only started following the club properly in 2009, here goes nothing! However, being born in 2000, I will include goals from then onwards! Tweet me (@LucasTBall) some of your favourites!
This is not ranked, just a top 10 (some may be in here based on what they meant for the club, rather than quality).
1. GARY ALEXANDER vs Scunthorpe (Coca Cola League One Play-Off Final, 24th May 2009)
What an incredible strike this was! An instinctive (half) volley from about 35 yards out beat Joe Murphy for power, swerve and dip- sending the 45,000 plus Millwall fans into raptures. A goal deserving of winning any game, but unfortunately Martyn Woolford's (who eventually played for Millwall) late winner meant the Lions had to wait another year for promotion.
2. NEIL HARRIS vs Tranmere (FA Cup Quarter Final Replay, 16th March 2004)
The build up play for this goal was absolutely superb, and the finish just as good! An incredible goal which proved to be the pivotal one in sending Wise's men through to the semis.
3. NEIL HARRIS vs Watford (Division One, 1st January 2002)
Not only was this goal a superb run and finish by record-scorer turned manager Harris, it was a goal that meant absolutely everything to him and the club. After being diagnosed with testicular cancer in his early 20's, many wondered whether the Southend-born lad would play again, but this was his first goal following his comeback.
4. NEIL HARRIS vs Crewe Alexandra (FA Cup Third Round Replay, 13th January 2009)
At Gresty Road on a cold Tuesday night, Harris scored his 112th Millwall goal to surpass Teddy Sheringham's record in 2009. Harris remains the Lions' record scorer. It wasn't the best of finishes, but a goal that saw us through to the Fourth Round and cemented Harris' place as a Millwall legend even further.
5. PAUL ROBINSON vs Swindon (Coca Cola League One Play-Off Final, 29th May 2010)
A scrappy goal from a corner, but one that was incredibly important nonetheless. "Robbo's" goal was the only one of the game in the 2010 play-off final, ensuring heartbreak did not occur at Wembley again just a year after losing to Scunthorpe.
6. TIM CAHILL vs Sunderland (FA Cup Semi Final, 4th April 2004)
THE goal that sent Millwall through to their only ever FA Cup Final! Paul Ifill intercepted a poor pass from one of the Sunderland backline, before cutting inside and having his shot saved, allowing Timmy to put the ball in the back of the net from just inside the box.
7. STEVE MORISON vs Bradford (Sky Bet League One Play-Off Final, 20th May 2017)
This will go down as Morison's most important in Millwall colours. Gregory's diving header was met by the former Stevenage fan at the far post, who had no trouble in beating the Bradford goalkeeper who were beaten by Millwall in the play-offs for the second consecutive season.
8. SHAUN CUMMINGS vs Leicester (FA Cup Fifth Round, 18th February 2017)
Millwall's historic cup run saw them become the first third tier side to beat three Premier League sides in the FA Cup in the same season. After being reduced to ten men against the then-Premier League Champions, few gave the Lions hope of reaching the quarter final, until Cummings' injury time winner!
9. SHANE LOWRY vs Charlton (Championship, 16th March 2013
Well, what a goal this was. As Millwall won yet another game vs Charlton (I've lost count of how many years it is now), Shane Lowry scored an absolutely brilliant free kick from around thirty five yards out!
10. JAMES HENRY vs Swindon (Coca Cola League One, 17th February 2009)
Henry scored some brilliant goals in his time at Millwall and plenty were sad to see him leave when he did. Originally on loan from Reading, he proved to be a shrewd signing by Kenny Jackett, and this fine late equaliser was just one example of his quality.
Josh Mcquoid's goal^
Note: Neil Harris' third goal at home to Bournemouth in August 2009 would have been included, but I could not find a YouTube clip.
