The 2018 Latvian Higher League was the 27th season of top-tier football in Latvia. Spartaks Jà «rmala were the defending champions, having won their second title in the previous season.
At the end of the 2017 season, Babëte were excluded from the league due to match-fixing. This resulted in METTA/LU ending up as the bottom-placed team. They were sent to the relegation playoffs against FK Progress/AFA Olaine. METTA/LU won, keeping them in the Latvian Higher League.
Babëte were replaced by the champions of the 2017 Latvian First League, Valmieras FK.
