圣诞节 是个发生于十二月十五日到三十一日的 季节性事件 ( 移动 and 则是十二月一日至三十一日)。圣诞节时 版礼物可以从敌怪以十三分之一(约百分之7.7)的机率获得，除了敌怪使用雕像生成。心也被换为糖棒、魔力星被换为蜜糖李。
在困难模式中， one of the items a present can contain is the 水晶雪球, which summons the 雪人军团. Defeating it enables the 圣诞老人 NPC, which spawns if valid housing is available, but only during the Christmas season.
- *Does not drop from 雕像-spawned enemies
- Christmas can be "activated" by setting your computer's date to a day between December 15th and 31st, and on the 主机版, disconnecting from Xbox Live/PSN and changing the console time. On mobile you should disconnect from automatic date/time updates, and set the time to any day in December, however this does not work for some devices, and for the 3DS version, go to System Settings and set the date there. However, if you wish to not change your device's time to avoid messing up scheduled programs, you can use applications such as RunAsDate to launch Terraria with a changed time/date.
- 移动版 1.1.5：Introduced. 圣诞 can spawn randomly any time during the Christmas season.
- The event has been updated, featuring several new items.
- One single present item drops instead of three different colors.
