Lee Andrew Gregory (born 26 August 1988) is an English professional footballer who plays as a striker for EFL League One club Mansfield Town.

[3] Following his release from the Blades' academy Gregory, began working as an electrician whilst playing for Northern Counties East League side Staveley Miners Welfare.

[5] In September 2009 he signed with Conference Premier side Mansfield Town, where he was told by manager David Holdsworth that he would be sent out on loan and then come back and stake a claim for the first team.

[12] Gregory finished the 2011–12 campaign in the Conference North as the club's top scorer with 18 league goals although promotion was missed out after losing to Gainsborough Trinity in the play-offs.

[11] On 30 June 2013 Gregory signed a new two-year deal with Halifax,[13] and finished 2013–14 with 29 league goals under his name, being the division's second top goalscorer, behind only Luton Town's Andre Gray.

[15] At the end of the campaign Gregory was attracting interest from Football League clubs with Championship side Millwall making a number of bids.

[18] Gregory was a regular in the 2014–15 season as Millwall struggled in the second tier and with relegation an inevitability, manager Ian Holloway was sacked in March 2014 and replaced by Neil Harris.

[19][20] Gregory scored a hat-trick in a 3–3 draw against Derby County on 25 April 2015 but it was in vain as Rotherham United defeated Reading to relegate Millwall to League One.

[24] Gregory scored 17 goals in the second half of the campaign bringing his total to 27 which helped the Lions reach the 2016 Football League One play-off final where they were beaten 3–1 by Barnsley.

[30][31] Gregory scored ten goals in 47 appearances in 2017–18 as Millwall had a fine return to the Championship narrowly missing out on a play-off spot by three points.

[49] He made his Wednesday debut coming off the bench against Doncaster Rovers on 14 August 2021[50] and a few days later against Fleetwood Town he scored his first goal for the club.
