Lachlan Blakiston (born 9 September 1998) is an Australian rules footballer who plays for the Essendon Football Club in the Australian Football League (AFL).
Blakiston played for the Cockburn Cobras in the Perth Football League prior to being picked up by South Fremantle in the WAFL Reserves in 2022. He moved to East Fremantle's reserves team in 2023, and by 2024 he was playing in their top side, averaging 16 disposals and over 33 hitouts a game.
Blakiston received attention during the 2024 AFL draft period. However, he was ultimately not selected by any AFL clubs during that time.
Blakiston was selected by Essendon with pick 13 of the 2025 mid-season rookie draft. He made his debut against Geelong in round 14 of the 2025 AFL season. He played eleven games in 2025, forced to play out of position as a key defender due to the large number of injuries at Essendon.
In September of 2025, Blakiston signed a one-year contract extension to the end of 2026. In March 2026, Blakiston extended his contract for a further two years to the end of 2028.
Updated to the end of round 3, 2026.
